President Siebert: So, listen, fellas, who's up for a little party this Saturday night? Open bar, good eats, might even be a few pretty girls.
Raj: Sounds great!
Howard: I'm in!
Sheldon: Hold on. Just because the nice man is offering you candy, doesn't mean you should jump into his windowless van. What's the occasion?
President Siebert: Just a little fund-raiser for the university.
Sheldon: Aha! The tear-stained air mattress in the back of the van.
