Woman Falls for Hilarious Fake Sonogram

If you've never seen a sonogram before, you kinda don't know what to expect or what you are going to see. So when a pregnant woman took her unsuspecting mom with her, it was a good opportunity to play a joke on her. And it's hilarious!

One of Jimmy Kimmel's cousins is pregnant and they decided to prank her mom -- Jimmy's Aunt Chippy -- who actually is a bit "chippy". Aunt Chippy had never seen a sonogram before, which is why this prank works.

Jimmy Kimmel's people put together graphics and images that are a bit far-fetched for a baby in the womb to be doing, but hey, if you don't know what you are supposed to be seeing, you'll probably believe it.

Aunt Chippy did.
