Public health joke, as told by Shama:

So this Bangladeshi woman married this man whom she had known for quite some time. However, being that they were good, pious people, they hadn't been exposed to each other's bodies at all until their wedding night.

On their wedding night, the man began to undress. The woman noticed a horrible looking mark on his elbow and asked what it was.

"Oh, that! That's left over from my elbolio. I've had it since I was a child."
"Don't you mean 'polio,'" the woman responded?
"No, no... elbolio!" the husband replied.

He continued undressing and the woman noticed an ugly rash on his legs.

"Oh my! Your legs! What's wrong?" the woman exclaimed!
"Oh, my wife. No worries. That is from my kneesles. It is not contagious anymore."
The woman responded, "Wait, do you mean 'measles?'"
Her husband replied, "No... I'm sure it's kneesles!"

So, the man kept undressing.
As he removed his underwear the woman's eyes grew large.

"... Don't tell me," she said. "Small cocks?"

Ha. Ha. Ha.
