Jimmy Kimmel is famous for entertaining people and what he did to his aunt in this video is absolutely hilarious.
When he learned that his cousin had become pregnant, Kimmel had the idea to make fun of his aunt because she had never seen an ultrasound - so was the perfect victim for his gag.
With the help of his team, he was able to create funny images of and ultrasound.
At first, we see a baby doing strange things. He applauds, picks his nose, gives them the finger and then even starts doing jumping jacks.
Then two babies appear, both with adult faces - one of them Jimmy - who then comes into the room to confirm the brilliant prank.
Check out the video below and be sure to share this with your friends to give them a good laugh.
