A blind man and his guide dog enter a bar and find their way to a barstool. After ordering a drink, and sitting there for a while, the blind guy yells to the bartender,

'Hey, you wanna hear a blonde joke?'

The bar immediately becomes absolutely quiet. In a husky, deep voice, the woman next to him says, 'Before you tell that joke, you should know something.The bartender is blonde, the bouncer is blonde, and I'm a 6' tall, 200 lb. blonde with a black belt in karate. What's more, the woman sitting next to me is blonde and she's a weight lifter. The lady to your right is a blonde, and she's a wrestler. Think about it seriously, Mister. You still wanna tell that joke?'

The blind guy says, 'Nah, not if I'm gonna have to explain it five times.

Good one!

no matter how many times I hear that one it's still good for a laugh

Wow, I'd never heard it before! Made me laugh though...
