Fool me a dozen times, and I should really see a neurologist.

Jillian Haker had an awesome 2014 of pranking her brother. Over and over again. With the same prank.

Like all pranks, it only got funnier the more times he fell for it. And he only got angrier.

There are only two reasons to do a prank on the same person this many times and Jillian confirms them both on YouTube. 1) Because you love the person you're pranking "so much!" and 2) You want to go viral enough to meet Ellen or Taylor Swift. You're on your way, Jillian. Hope your bro gets to go, too.
