How many line cooks does it take to screw in a lightbulb?
Three. One to do it, and two to say that they did it better at the previous restaurant they were at.
Okay, so listen up, buttercup. This joke is all about how line cooks, those peeps slinging food in restaurants, always think they know best. It only takes one to actually change the bulb, but the other two just gotta chime in about how they were total pros at the last place. Get it now, genius?
