Tom Kenny Squarepants

SpongeBob SquarePants makes no sense. Created by marine biologist turned animator Stephen Hillenburg, the character lives in an underwater pineapple in a place called Bikini Bottom. He keeps company with a lumpy starfish named Patrick, a cranky neighbor named Squidward, a greedy crab of a boss and an evil plankton.
But now, 10 years after SpongeBob made its on-air debut, the show is still wildly popular. One week last month, nine of the top 20 shows on cable were SpongeBob cartoons.
Tom Kenny, who provides the voice of SpongeBob, calls the character "pretty bipolar ... his highs are very high but he can also be dashed into the most abject sorrow."
Kenny says he'll gladly be the voice of SpongeBob for another 10 years.
"Even if the show doesn't go for 10 years, I'll be the guy pushing a grocery cart around with a tinfoil hat on his head going 'Hey you know who I used to be?' " he jokes.
