Jimmy Kimmel has a rocky relationship with children. Every October, the late-night host encourages parents to tell their kids that they ate all of their Halloween treats  and film it for millions to see. It's a prank that leaves many children in tears and slightly traumatized. In an effort to mend his relationship with little ones, Kimmel gave kids a chance to prank their parents. Over Father's Day  weekend, Kimmel asked kids to scream, "hop on pop," and then jump up and down on their sleeping dads. While this prank made kids, moms, and audience members laugh out loud, it left several fathers screaming in pain.
