Juggling Innuendo

Alright, listen up, ya goof. You're the kinda person who probably thinks a 'juggling ball' is something you kick. Here's the deal: this joke plays on the double meaning of "balls". On one hand it means the literal, you know, balls used in juggling. On the other hand, it's slang for courage. So, the man isn't bad at juggling, he's just too scared. Get it now?
