You gonna keep running your mouth off about it or are you gonna shut up and go find food? I have other stuff I could be doing, you know.

[Ja'far looks incredibly unimpressed. Food is something you stick some poison in to build up your immunities, eat as fast as possible, then try to keep down because, you know, poison. He's not particularly interested in understanding people or changing the world or whatever, if that's indeed something you can do by eating. It's just as likely that Sinbad is talking out of his ass.]
