Dad loved to tell this joke and we loved to hear it. :)
"A blind man walked into a bar and asked for a beer. As the bartender served him a beer he said, 'Ok, I realize that you're blind so your beer is in front of you.'
The blind man thanked him and asked, 'Hey, wanna hear a good blonde joke?'
The bartender, a little angry said, 'Because of your blindness I want to tell you that I'm 6 feet 4 inches tall, weigh 250 pounds and I'm blonde. The guy at the end of the bar, my brother, is 6 feet 6 inches tall, weighs 280 pounds, is a sumo wrestler, is also blonde, and the guy at the pool table is 6 feet 4 inches tall, is a Golden Gloves boxer and is also a blonde. Now...do you still want to tell that blonde joke?' asked the bartender.
After thinking a few seconds, the blind man said...'Not if I have to explain it three times.'"
