Funny story... Zac recently told a reporter about the time that he felt "mortified" when he got his foot trapped in a theatre seat. It happened durning the filming of High School Musical 3: The Senior Year.
'I don't know how it happened, but my foot slipped through a theatre seat during filming and I couldn't get it out," he was quoted as saying. "It was so funny because the had to take the seat apart to rescue my foot. The cameras had to stop rolling and people were brought on the set to unscrew the bottom of the chair."
