Jimmy the pig
Jimmy, dressed as a talking pig, befriends two young girls at the State Fair. But just because they believe in talking pigs, that doesn't mean they'll let him boss them around.

MATCH-UP 3: JOKE'S ON DAD

Hey Jimmy Kimmel, I unplugged the TV during the Big Game
This type of Super Bowl black-out only affects houses with pranksters. Viewers were encouraged to unplug the TV at a crucial moment in the game, and many were up to the challenge. Jimmy promised that only 30 people were hospitalized over this.

MATCH-UP 4: TRICKING YOUR KIDS FOR A LAUGH

Hey Jimmy Kimmel, I told my kids I ate all their Halloween candy
What could be meaner than tricking your kids into believing all their Halloween candy is gone...because you ate it? Jimmy first asked parents to pull this prank in 2011, and it's been a hit every year since.

Hey Jimmy Kimmel, I gave my kids a terrible present
OK, we thought of something that might be meaner than stolen Halloween candy: getting a half-eaten sandwich for Christmas. We'd say they should go on Santa's nice list for putting up with this, but some of these kids had pretty major meltdowns.

MATCH-UP 5: POOR AUNT CHIPPY

Aunt Chippy falls for April Fools' Day prank
Jimmy's favorite prank subject agreed to do an interview with her local ABC affiliate. Too bad Jimmy and Cousin Sal knew exactly how to turn it into a disaster and make Chippy go into full crazy Italian aunt mode.

Cousin Sal and Jimmy Aunt Chippy sonogram prank
It's cruel enough to call Aunt Chippy "as sweet as a shot glass full of gasoline," but Jimmy took advantage of how gullible she can be, too. In her very first sonogram viewing, the "baby" made a pretty rude hand gesture...and did some jumping jacks.

MATCH-UP 6: THAT'S NOT JIMMY!

Matt Damon's revenge
For 10 years, Jimmy "ran out of time" to have Matt Damon as a guest on the show. When the actor finally got his revenge and took over the show, it made us laugh out loud...but also squirm in our seats.

Take a photo with "Jimmy Kimmel"
People claiming to be fans of the show lined up to get a photo with Jimmy. The catch was that they were greeted by a guy who only kind of looks like him. That didn't make a difference for most of them.

MATCH-UP 7: ON THE STREET

Jimmy asks pedestrians for their password
Does it count as a prank if the person knows what's going on? People on the street were asked for their passwords, and they gave them up without much of a fight.
