ROBIN WILLIAMS FAN SHOWS HERSELF

After those vicious “Death To Smoochy” reviews, Robin Williams REALLY felt like the. . . er, butt of a bad joke when a femme fan accosted him in an elevator, ranting: “I’m your biggest-ever fan — so I got a special tattoo. Want to see it?” Loony Lass quickly dropped her jeans — exposing a caricature of Robin’s kisser on her left derriere cheek! Tongue-tied and red-faced, Robin lickety-split when the doors slid open!
