A blind guy walks into a lesbian bar by mistake. He finds his way to the counter and orders a drink. After a while, he says loudly to the girl behind the bar: - "Hey, do you want to hear a really good joke about blondes?" Silence falls in the bar and in a deep, gravely voice the lesbian to his left says :- "Before you tell your joke, there's something you should know...The girl behind the bar is blonde, the girl by the door is blonde and I'm a 6 foot, 16 stone blonde with a black belt in karate. The girl to my left is blonde and she lifts weights. The girl to your right is blonde and a professional wrestler. Think about it seriously, Mister. Do you still want to tell your joke?" - "Not if I'll have to explain it five times..."
