It's Quiz Time

[The Seer]

Can you guess the perpetrators?

[HighHard1]

Fucking Scandanavians.

[Roach]

Maxine Waters

[Dr_Phibes]

Richard Chamberlain.

[mvscal]

Rhymes with triggers?

[HighPlainsGrifter]

Those cops, probably.

oh good quizzes are a good way to keep one sharp. Thank you Seer for getting the ball rolling.

Sorta hearkens back to the old "OCMike's Hump day Challenge" from yesteryear.

here's one concerning my favorite subject:




I got all of 'em correct. Well, the level of competency this vid is testing, zero excuses if I don't.


be interesting to see what quizzes the rest of youse post from your wheelhouse.

maybe Seater can find a good quiz about aviation?

m2 could post one testing knowledge of The City?

HighPlainsGrifter could dig one up about the finer points of being a ruthless capitalist industrialist pig bent on crushing the souls of the proletariat?


Smackie Chan know any good music quizzes?


I'm sure mvscal could proffer an apt history exam.

Roux and 88 with a law test?

Mikey is something of a polymath, so hard to say what he might do.

I"m typing Python's nic just so he's on the list here.

it's up to wolf-O to work up a graffiti quiz.

kcdave might regale us with one about cooking

Diego could do a kindness with a politics quiz vid

Sven, our economist should be able to get us one that tests our skills concerning micro and macro

phibes is the poster best suited to bring us the Canadian quiz, which all of the rest of us will fail mainly because you know, Canada is just a fictional place featured on South Park




good thing AP isn't around because I doubt anyone is interested in his expertise...

I'll post one. Please hold.

good one Mikey! I took calculus... just not that calculus

[Roux]

I have a 25% chance of guessing the right answer on Mikey's quiz. And yet if I actually took the quiz, I'd probably score less than 25%

[Mikey]

good one Mikey! I took calculus... just not that calculus

Google Generative AI is your friend.

That was an upper division class for Engineering Control Systems. It's all about using an iterative process to resolve complex differential equations that have no explicit solution. Part of the reason I switched to Mechanical Engineering, where most of the problems at least have a real world analog.

What were Sir Isaac Brock's last words at The Battle of Queenston Heights?

1: Dragoon helmets are for assholes

2: Destroy the enemy! and no giggling

3: Don't let my fall interfere with the men

4: If an American offers to surrender, give him a potato. They like that. It's what I heard. If you want to go with a fruit basket, it's up to you.

I’ll take #5 - all of the above.

Couple weeks news with modest media coverage...wonder why?

Alabama husband, father of two making national headlines as he ‘fights for life’ after unprovoked hatchet attack in Arizona



Jacob Couch and his wife Kristen were traveling back to Arab after spending nearly a year in Los Angeles coping with the loss of their stillborn son. But before they could make it home, Jacob Couch was violently attacked by a hatchet-wielding assailant.

In an interview with KOLD-TV, Kristen Couch said a man attacked her husband at a bus stop as he bent down to pick something up, defenseless.


Video shows alleged Dallas school shooter entering through "unsecured" door, affidavit says





Frisco track meet stabbing suspect released after bond reduced to $250,000

Austin Metcalf, a junior Memorial High School in Frisco, was stabbed after he allegedly got into an altercation with 17-year-old Karmelo Anthony, who is a student at Centennial High School in Frisco. Reports indicated that the dispute began after Metcalf told Anthony he was sitting in the wrong spot. Metcalf was stabbed in the heart.

Ima rassis

Take the racist test here:
https://www.idrlabs.com/racism-scales/test.php

"This makes you:
26.81% more prone to general racism than the average person.
21.27% more prone to socio-historical racism than the average person.
25.93% more prone to perpetual foreigner racism than the average person.
24.9% more prone to racism than the average person overall."

A lot of bullshit but amusing. 5 minutes.

[Sudden Sam]

Obviously the kid in Dallas who shot schoolmates should be released with no charges. He felt threatened.

Same with the kid who stabbed a young man to death. Everyone should carry a large knife to a track meet.

Why are these innocents being held?

Are you implying that because some douchebags commit horrible crimes, that makes it OK to imprison and/or deport, without due process, people who haven’t committed any crimes…just because?

Because that’s sure what it looks like.

[Sudden Sam]

I’m confused as to how you’re interpreting things today so I think I’m going to do the last few shrooms that I’ve had stashed for about a year. maybe I can catch up with you.

[The Seer]

Fairness in reporting...This one will probably be page ONE for a month...the others...not so much...Unless of course he turns out to be a beta male lefty.

Who is Phoenix Ikner? FSU shooter who used mom's gun in college shooting

[Mikey]

I’m confused as to how you’re interpreting things today so I think I’m going to do the last few shrooms that I’ve had stashed for about a year. maybe I can catch up with you.

You asked “why are these innocents being held?” after describing a couple of horrible crimes. Why did you ask that question? I don’t believe you think that they are innocent (maybe you do) and I don’t see anyone seriously asking that question.

So this must be some kind of facetious question. Maybe you’re trying to run some kind of smack on folks who ask this about people who actually are innocent (as has been shown about a whole lot of people being rounded up by Dear Leader and his gang). Should we not be asking that question about people who actually are innocent, or are you In line with the “a few errors might be made but we can’t do anything about that” crowd?

Just wondering why you put that in there.

[Sudden Sam]

The comment had nothing to do with the prez or the dude in El Salvador. Good grief…

I was being sarcastic about the specific incidents I mentioned.


BTW, if that’s the FSU shooter, he looks crazy as all fuck. Like he’d take your head off with a hatchet crazy.

[Rootbeer]

FEMALE COPS!

I wonder if they are really "female"

I think it's about time to add a new gender....the XYX gender for the people like --->

To be fair, there are people that aren't either XX or XY.
