Useless Bus Driver

Okay, listen up buttercup. The joke is playin' on the double meaning of "work." You see, a bus driver's job is to drive, but if they "don't work," they're also useless. It's called a pun, and judging by the fact that you need me, Explain Bear, to explain it to you, you probably didn't get it. I bet you like to eat honey. So basic.
