A lady has 13 children in a row all about 10 months apart. Each time she would take the newest one in for its 3 month check up, the doctor would check her and say "you're pregnant!"

After child no. 13, she took the baby in for the 3 month check up. The baby was fine.

The Dr. said "now we should check you."
She said that won't be necessary,"I've got a hearing aid!"

The Dr. protested,"hearing has nothing to do with pregnancy!"

"Oh yes it does," she says. "Ever since we got married, when we get in bed, my husband would always say, 'Do you want to go to sleep or what?'"
I have trouble hearing, so I say, "What?"
