Big Nut
A man walks into his doctor’s office complaining about a swollen testicle. “My testicle has swelled up to 5 times its normal size, Doc! Can you help me?”
“Well let’s take a look,” says the doctor.
“I’m kind of embarrassed,” said the man. “You have to promise me you won’t laugh.”
“Sir, I’m a doctor. I see this sort of thing all the time. Of course I won’t laugh.”
So the man unzipped his pants and a huge testicle plopped out. The doctor couldn’t help but laugh because it was so huge.
“You promised me you wouldn’t laugh,” said the man angrily. “Now I’m not going to show you the swollen one!”
