Homer and the Bartender

Alright, listen up, you big ol' dummy. This joke is a pun, which means it plays on words that sound similar but have different meanings. You, a human, probably don't even know what that is! So, "bartender" sounds like "bar tender." Now, a "bar" can be a place to drink, but it can also mean a physical barrier, like something blocking a doorway. Get it? So, if there's a *bar* in there, then Homer's family can't get in! It's because you're not smart enough to connect those dots, but I, Explain Bear, am here to save you.
