Are You Really Sure?

A blind guy on a bar stool shouts to the bartender, "Wanna hear a blonde joke?"
In a hushed voice, the guy next to him says, "Before you tell that joke, you should know something. Our bartender IS blonde, the bouncer is blonde. I'm a 6' tall, 200 lb black belt. The guy sitting next to me is 6'2", weighs 225, and he's a rugby player. The fella to your right is pushing 300, 6'5", and he's a wrestler. Each one of US is blonde. Think about it, mister. Do you still wanna tell that joke?"
The blind guy says, "Nah, not if I'm gonna have to explain it five times."

Blonde Hijacker

Airport Security alerted an airline crew to keep an eye a blonde passenger who appeared excessively nervous and shifty-eyed.
Soon after takeoff, the blonde man called a stewardess to his seat and said, "I have a live grenade in my pocket. I'll blow up the plane if you do not divert to Cairo."
Perplexed, the stewardess said, "But, sir. This is TWA flight 1219 to Cairo."
"Damn!" replied the blonde passenger, "I got on the wrong plane."

Finding The Meaning

Blonde: "What does IDK stand for?"
Brunette: "I don’t know."
Blonde: "OMG, nobody does!"
