my mother

My parents and I were watching some forensics-type show where this woman was going to be a surrogate for her daughter who couldn't get pregnant.

Conversation:

Mom: I would do that for you. I'd be your surrogate.
Me: ...You don't have a uterus.
Mom: *long pause*
Me: You had a hysterectomy two years ago.
Mom: Oh...right. *uncontrollable laughter* Well, I would!
Me: Thanks, Mom.
