A Bus Full of Children

Alright, listen up, smarty-pants. So, the joke asks what's long, yellow, and can't swim. You'd think it's a banana or something, right? Nope! It's a bus full of children. Why is this funny? Because buses are typically yellow and long. And kids can't swim if they're trapped inside of a bus at the bottom of a lake. Get it? You probably don't, judging by the dumb jokes you tell.
