No, this isn't the Dos Equis TV pitchman imploring you to "Stay thirsty, my friends," or even an accidentally paroled Unabomber. But who is this hirsute honcho? We'll give you a hint: This Oscar-winning actor usually grows facial hair for serious roles, but shaves off the scruff for comedies. If that doesn't clue you in to who this beardo is, you can find out on the jump.
It's Robin Williams! And true to form, he's gone all furry for a drama—this time playing the lead in the Broadway play, Bengal Tiger at the Baghdad Zoo, where he's getting great reviews. What an awesome way to go incognito!
