blind man walks into a bar.
'can i tell a blonde joke?' he asks
A blonde walks up to him and replies 'well, there's a blonde heavyweight champion stood behind you; a blonde black-belt tae-kwon-do woman on your left; on your right a blonde expert swordswoman with two extremely sharp swords; a group of blondes with hound-dogs that they could set on you; and me in front of you - a blonde sumo-wrestler... are you sure you want to tell this blonde joke?'
The blind man thinks for a moment and says 'not if i have to explain it to each of you.
