Jay Leno wins more votes for funniest late-night host

One out of every four Americans (24 percent) say the Tonight Show's Jay Leno is the "most likely" to make them laugh, according to a new 60 Minutes/Vanity Fair survey. Leno got more votes than any of the other late-night show hosts.

Coming in at a distant second was the Late Show's David Letterman with 13 percent. Third was Late Night's Jimmy Fallon.

Another finding from the survey: One-third of Americans said DMV workers had the least sense of humor. After DMV workers, Americans chose airport workers (27 percent), toll collectors (20 percent) and finally night club workers (9 percent).
