"That Old Pair of Jeans" is a song by English electronic music producer Fatboy Slim, released on 26 June 2006 as a single from his greatest hits album The Greatest Hits – Why Try Harder.

It features vocals from American rapper Lateef the Truth Speaker.

Fatboy Slim commissioned comedian and juggler Chris Bliss to perform to the song in front of a live theatre audience for a music video.

The video expanded into a MySpace contest to "Juggle to music like Chris Bliss".

John Augustus "Gus" Tate won the competition[3] and Angie Mack received honourable mention as the "Non-Juggling Winner" as the video so impressed Fatboy Slim.
