Banking Career

Listen up, buttercup. This joke is playing on the double meaning of the word "interest." See, there's "interest" as in, like, bank interest, where you get money. But then there's "interest" like when you're interested in something, like when you're interested in eating a tub of lard. So, he used to work at the bank, but then he wasn't interested anymore, get it? I know, I know, it's a real head-scratcher for a simpleton like yourself.
