Clooney told Larry King he had bell's palsy, where half of his face was paralyzed, when he first started high school at age 13.

"It takes about nine months to go away," said Clooney who came down with symptoms after watching the film "The Pride of the Yankees." "It was the first year of high school, which was a bad time for having half your face paralyzed."

Clooney told NPR it forced him to make fun of himself which is an important part of being famous.

The actor told Esquire he was a good student, receiving A's and B's, at least in elementary. "I was a much better student than I thought I was. I had all A's and a B. So that's not so bad," said Clooney in 2008.

Clooney was also part of drama club and was prince of his senior prom.
