Blind dude walks into what turns out to be a lesbian bar and sits down at the bar-he orders a drink and says to the female bartender- 

**do you want to hear a bleached brunette joke? 
The bartender replies- 
**Before you start you need to know that I am bleached brunette with a black belt in karate and am licensed to carry a firearm. There is a bleached brunette seated to your right that is on her period and works construction and to your left is a bleached brunette that was just released from prison for murdering her husband. Knowing all of this, do you still want to tell your bleached brunette joke? 
The blind dude takes a sip out of his drink and says- 
**Nah, nevermind, if I am going to have to explain it three times it ain't worth it
