An engineer, chef, and a mathematician go out drinking To their favorite bar and grill. Well they're having some drinks and laughing when a fire starts behind the bar. Seeing the staff panicking, the engineer quickly calculates exactly how much water he'll need to put it out and runs in the back for a bucket. The chef, from his own experience can tell its a grease fire so he runs in back to find salt. The Mathematician looks at his friends, then to the fire. Upon realizing there is a solution, he promptly continues drinking.
