'Jeopardy!' host puts facial hair future in hands of fans

The 'stache is back for "Jeopardy!" host Alex Trebek. But will it stay?

On Monday, for the first time in 13 years, Trebek appeared with the signature mustache he shaved off in 2001.

Now, Trebek is putting his facial hair future in the hands of fans. He's asking viewers to weigh in on Facebook and Twitter using the hashtags #KeepItTrebek or #ShaveItTrebek.

No word on how long you have to persuade the game show host. So if you have a strong opinion either way, get online and weigh in!
