Eighty-two-year-old firecracker Cloris Leachman exposed her quick wit during an appearance on Comedy Central’s "The Roast of Bob Saget." The "Young Frankenstein" and "Mary Tyler Moore Show" legend stole the show when she opened her comments by saying, "I am not here to roast Bob Saget. I’m here to f—- John Stamos."

Leachman’s award-winning career started in the late 1940s. She studied at the Actor’s Studio under the famed Elia Kazan. But she is best remembered for her role of nosy landlady Phyllis Lindstrom on the "Mary Tyler Moore Show," and as Frau Blücher in the original Mel Brooks movie, "Young Frankenstein."

The eight-time Emmy Award winner brought down the house with naughty references to handsome John Stamos as well as her late friend Jack Benny. Her risqué remarks can be viewed below:
