"I'm the Slime" is a 1973 single by Frank Zappa and The Mothers from the album Over-Nite Sensation. Different live versions can be found on Zappa in New York and You Can't Do That on Stage Anymore, Vol. 1 which the version was performed on the same night as the majority of Roxy and Elsewhere. "I'm the Slime" and its b-side version of Montana were put on Zappa's best of Strictly Commercial. It was performed in concert from 1973 to 1977 and 1984.

The song contains two parts; the first part is a riddle of insults in the form of "what am I?"

"I am gross and perverted. I'm obsessed 'n deranged. I have existed for years, but very little has changed. I'm the tool of the government and industry too, for I am destined to rule and regulate you. I may be vile and pernicious, but you can't look away. I make you think I'm delicious, with the stuff that I say. I'm the best you can get. Have you guessed me yet?"

The second part discusses the evils of the answer to the riddle, the various things seen on television.

For the recording of this song (and most of the Overnite Sensation lp), Zappa used Ike Turner's Bolic Studios in L.A.. By virtue of this arrangement, Turner offered up the use of the Ikettes (including Ike's then wife, Tina Turner) to sing back up vocals for various songs on Over-Nite Sensation including "I'm the Slime". Ike Turner insisted that Zappa only pay the Ikettes $25 per song, to which he reluctantly agreed. After hearing one of the recordings in the studio, Ike, exclaimed "What is this shit?" and later insisted that Tina and the Ikettes would not be credited on the album.

Zappa performed "I'm the Slime", as well as "Purple Lagoon", and "Peaches en Regalia" in his first of two appearances on Saturday Night Live. NBC announcer, Don Pardo was utilized for his distinctive delivery for the second movement, (or B section) of "I'm the Slime". Zappa described this as the, "highlight of [Don Pardo's] career." Pardo performed at the Palladium, in New York City in December, 1976 on "I'm the Slime", and parts of "Punky's Whips" and "The Illinois Enema Bandit", documented on Zappa in New York.
