George Clooney's garnering laughs as a mustachioed playboy in a new Martini commercial making the rounds on YouTube.

In it, the leading man, who boasts Clark Gable lip hair, is at a fancy outdoor party and races actress Shannyn Sossamon for a drink refill. When she hands him a glass, he dramatically rasps, "Bellissimo!"

"It's nice to see George be so funny," one fan comments.

Clooney, 47, has been a pitchman for the beverage company since 2004.
