A blind man walks into a pub and finds himself a seat at the bar, he orders a pint and the barman brings it to him.
He says to the barman “do you want to hear a good dumb blonde joke?”
The barman says “look mate, I know you can’t see, but I’m six foot seven, and I’m an ex pro wrestler and I’m blonde. The guy sat to your left is my mate John who’s an ex heavyweight boxer and he’s blonde. The guy on your right just got out of prison for beating four guys half to death and he’s blonde. Also sat at the table just behind you are two special forces guys on leave and both of them are blonde. So do you still want to tell your dumb blonde joke?”
And he says “nah, not if I’m going to have to explain it five times.”
