An oldie, but a goodie

An old, blind Marine accidentally stumbles into an all-girl biker bar, completely unaware of his surroundings. After feeling his way to the bar, he takes a seat and orders a shot of Jack Daniels. 

As he settles in, he suddenly yells out, "Hey, anyone here wanna hear a blonde joke?" 

The room goes dead silent. From beside him, a deep, authoritative voice calmly responds, "Before you go any further, I think you should know a few things." 

The voice continues: 

"First, the bartender is a blonde woman with a baseball bat.

Second, the bouncer is also a blonde woman.

Third, I'm a blonde, 6-foot-tall, 175-pound black belt in karate.

Fourth, the woman sitting next to me is a blonde professional weightlifter.

Finally, the lady on your other side is a blonde professional wrestler."

The room stays silent as the Marine pauses to process what he just heard. 

After a moment, he chuckles softly and says, "You know what? Forget it. I don't feel like explaining the joke five times."
