Here's the dialogue:
Sporting goods manager (Seth Rogen): I'm looking to hire guys I don't mind hanging out with for 12 hours a day. You guys seem like cool guys. Got hair similar to mine, you wear tuxedo's to the interview, that's funny, it's ironic, I get that. Underplaying tho whole formality of it. I think that's funny as hell. So...lets do this, you know? You guys are in, you're hired. Unless you're the weirdest guys ever and I don't see it.
Brennan: Great.
(Dale farts for about 10 seconds, shocking the Sporting goods manager)
Sporting goods manager: ...Was that a fart?
Dale: I don't know.
Sporting Goods manager: I can taste it. On my tongue.
Dale: Okay, I'll be honest with you. I did fart.
Sporting Goods manager: Is that onion? Onion and...onion and ketchup. It stinks. This is a small room...
Brennan: Sh!t.
Sporting Goods manager: Okay, now the tuxedos seem kinda fukced up.
Seth Rogen views the guys as TOO WEIRD to be hired! At first, he thought the guys were humorously smart to dress up in tuxes for a minimum-wage job.
