Blind man enters bar.

He sits at the counter, and orders a drink. After loafing for a while, he says to the bartender:

"Hey, want to hear a blonde joke?"

The atmosphere suddenly becomes tense, and silence falls around him. Suddenly, a deep feminine voice towers over to him: "I bench press 800 pounds at the gym every day. My girlfriend here has a black belt in judo, karate, and sumo. The bartender here isn't too slow himself, and he's trying to serve up four full tables. And you know what, buddy? We're all blondes here. Now think about it ... Do you really want to finish that joke?"

The blind guy shakes his head and says, "What do I look like? r/Jokes?"

*edit:*

Suddenly the crowd gets rowdy, and begins going after the blind man. The blind man just sits and laughs.

"Try your best! You don't think I know what a self-post is!?"

Try as they might, their blows suffer no ill-effect upon the blind man.
