Sacha Baron Cohen ‘Kills’ Charlie Chaplin’s Oldest Living Co-Star

Sacha Baron Cohen isn't known for his tact (remember when he sat on Eminem's face at the MTV Movie Awards … or when he Bisquick-bombed Ryan Seacrest at the Oscars?), but the star took his antics to a whole new level at the Britannia Awards on Saturday.

The "Borat" actor was there to receive the prestigious Charlie Chaplin award, which honors a comedic talent. Presenting the award to the star was a woman identified as 87-year-old Grace Collington, Charlie Chaplin's oldest living co-star.

Grace entered the stage in a wheelchair as Salma Hayek told the audience Grace had starred with Chaplin in the silent film "City Lights" in 1931, when she was only 5. As the elderly actress handed Sacha Charlie's cane from "City Lights," she cooed, "This is for you."

Sacha seemed truly touched, and delighted his fellow guests at the Beverly Hilton by imitating the icon's famous walk — but then something happened… and by "something happened" we mean he stumbled and fell on poor Grace, sending her (and her wheelchair) careening off the stage.

Gasps of horror were soon replaced with laughter, however, as the comic continued his acceptance speech while Grace lied motionless on the floor, and the attendees realized it was all a prank. (Whew!)

"Grace Collington is the oldest, sorry, was the oldest living [Chaplin co-star]," he quipped. "I dedicate my award to her. It's obviously a tragedy, but on the bright side, what a great way to go. She'll probably make the Oscars In Memoriam section," he explained as her "body" was carried out of the room.

"I'd like to say a few words to her family," he mused. "Do not try to sue me. If you decide to get the lawyers involved, I will take you down just like I did your granny. The cane that woman forced on me was clearly defective and I've got lots of witnesses."

"Anyway, tonight is not about her, it's about me," he added. And with this stunt he pulled, it may have been. Well, at least until Julia Roberts got onstage barefoot and spoke about her pal, "George Looney."
