For this year's Father's Day YouTube Challenge, the late night host called on kids to prank their dads by yelling, "I love you," at them as loud as possible — and filming the ensuing freak-outs, of course. Kimmel then aired a selection of the best submissions on Monday's episode of Live!
"In years past we've asked you to spray dad with a hose on Father's Day, to serve him breakfast in the shower, to dump breakfast on him in bed," he explained. "We've had a lot of very bad ideas. But this year the challenge was simple — sneak up on your father and yell, 'I love you, dad,' as loud as you can. I was starting to think this might not work, but I was very very wrong."
The results were definitely not disappointing.
