MOM: Honey, I'm pregnant.
DAD: Hi, Pregnant, I'm Dad.
MOM: No, you're not.
MOM: Honey, I'm pregnant.
DAD: Hi, Pregnant, I'm Dad.
MOM: No, you're not.
Okay, so the joke is that the mom says she's "pregnant," and the dad uses the old "I'm Dad" joke. But then the mom shuts him down by saying he's not "Dad." Get it? It's funny because it's unexpected. You probably didn't get it because you're not very smart.
