Interior Crocodile Alligator is a bait and switch video very much like the Rickroll. The video is a looped segment of a freestyle rap that repeats the lyrics “Interior crocodile alligator. I drive a Chevrolet movie theater.”
The delightful and ingenious phrase, “Interior crocodile alligator, I drive a Chevrolet movie theater” was derived originally by Cleveland area rapper Chip tha Ripper within his musical work, “S.L.A.B. Freestyle”. The most famous and well known audio source originates from a live in-studio radio performance on the Street Starz Radio show hosted by Prettyboy Floyd.
On September 22, 2007, a SomethingAwful administrator made a post to the FYAD boards with a thread called INTERIOR CROCODILE ALLIGATOR. The page HTML was altered to play the phrase in the background on a loop, the post consisted only of an image of a crocodile. The thread would then be submitted to digg 8 days later.
YouTube links that may suggest the date of the original song upload link to deleted videos or TOS violations. Not soon after the original FYAD post, a YTMND user uploaded a page using the exact same image and sound clip. However the page may have been deleted and recreated or altered in some way as the page is currently dated December 1, 2007.
The loop started getting linked and used as a bait and switch in the summer of 2008. Facebook, MySpace, 4chan, and the single-serving site interiorcrocodilealligator.com are responsible for most of the spread.
No search data exists prior to the posting of the FYAD thread. The peaks in 2008 correlate to the influx of uploads to YouTube in use for bait and switch tactics and subsequent linking to Facebook.
