TV Mayhem was a British children's short-lived Saturday morning television series that was originally a replacement for Hey Hey It's Saturday after it was cancelled and aired from September 1991 for just six weeks on the breakfast television channel TV-am. The show was presented by Chris Evans, who later went on to co-host The Big Breakfast in 1992 on Channel 4. Cartoons that were aired included all the animated segments from Wake, Rattle and Roll (which were Fender Bender 500 and Monster Tails) and Bill and Ted's Excellent Adventures.
