An old, short-sighted cowboy stumbles into an all-girl biker bar by mistake. He feels his way to the counter, settles onto a stool, and orders a shot of Jack Daniels 
.
After a minute or two, he hollers,
“Hey bartender! Wanna hear a blonde joke?”
The place goes dead silent. 
In a deep, intimidating voice, the woman next to him says,
“Before you tell that joke, Cowboy, you should know five things:
The bartender is a blonde, and she’s holding a baseball bat. 
The bouncer is a blonde with a billy club. 
I’m a 6-foot-tall, 175-pound blonde with a black belt in karate. 
The biker next to me is a blonde and a professional weightlifter. 
The lady to your right is a blonde and a former U.S. Marine. 
Now think really hard, Cowboy…
Do you still want to tell that blonde joke?”
The old cowboy pauses, takes a slow sip of his JD, then says,
“Well heck no… not if I’m gonna have to explain it five times!”
