"I have this mustache, and the reason I have this mustache is, when I was young, my father had a mustache ... growing up, it embarrassed me," the Scott Pilgrim vs. The World star explained to Jimmy Kimmel on Wednesday.

"I'm expecting a child in December," Jason revealed. "I decided to grow out this mustache, so when we take photos, my boy or girl, whatever it is, they will be embarrassed. So I am now thinking of ways to embarrass my unborn child."
