"Mother-In-Law" joke

John was in a bar looking very dejected. His friend, Steve, walked over and asked, "What's wrong?"

"It's my mother-in-law," John replied, while shaking his head sadly. "I have a real problem with her."

"Cheer up," Steve said. "Everyone has problems with their mother-in-law."

"Yeah," John answered. "But not everybody gets theirs' pregnant."
