As someone who teaches the occasional university undergrad course, this is more real than you might think. Here an excerpt:
TELLER: Right. So, yeah, we split the plutonium atom I guess. And make a weapon out of it.
BETHE: When is this due anyway?
TELLER: I think tomorrow.
TELLER: I know, right? I mean we shouldn't have put it off, but ... still sucks.
BETHE: I have another class with one of the Soviets, and he says theirs isn't due until 1949.
BETHE: I know, right?
TELLER: I knew we took the wrong section. And no wonder the Russkies were out last night.

I believe the UN also conducts its meetings in the same way. With the exception, that I believe everyone would also be smoking.
OMG I am STEALING this for my class tomorrow. The LITTLE BEASTIES all of whom are science students, REFUSE to do their f-ing group projects. Apparently their science will take place in some isolated lab a la the artist.
