Bowling Ball Holes

Alright, listen up, genius. The joke plays on the double meaning of "balls." In bowling, the bowling ball literally has holes for your fingers. But "balls" is also slang for, well, you know...the family jewels. So, the joke is that bowlers are in pain because their *actual* balls have holes in them. Get it? I didn't think so, you're probably one of those people who still uses internet explorer.
