Jim Carrey stopped by Jimmy Kimmel Live on Thursday night to promote Dumb and Dumber To, in which he reprises his 1994 role as clueless limo driver Lloyd Christmas.
But it wasn't long before he left the studio for Hollywood Boulevard, where the 52-year-old actor invited strangers into a barber's chair.
Carrey admitted that he had never cut hair before, but proceeded to snip and shave strangers' hair into Christmas' signature bowl cut.
"It symbolizes the control I have over the mind of my fans," Carrey said when he went a little overboard on one woman's blond locks.
Dumb and Dumber To hit theaters on Friday.
