Father's Day is next week, and as you get ready to recognize your old men, be thankful they haven't pulled any of these tricks - and if they have, you can always seek therapy.

High Five has viral video gold this week, starting with a high schooler who pisses himself in front of his school. Also fire extinguishers sprayed in the eye, a huge flaming mishap in the kitchen, and several failed and one successful drunken backflips.

For every perfect prank, there's a prank that backfires, resulting in hilarious self-pwnage. Here are 5 people who suffer the wrath of Karma... our second round of top 5 backfires.

People really brought their A game this April for the Break prank contest. These are all gems featuring a mother scared into labor, a rat trap revenge, and more.

Whether these accidental - or on purpose everyone gets hurt with little help from their friends surprised sleeper as his bunkbed is kicked to the ground, a weightlifter nutshotted at an inconvenient time, a punk kid scraped with barbed wire and burned by his friends. All this and a cute girl kicks a guy in the face, and hes not the one who even gets hurt.
