Get Stuffed (1991)

GET STUFFED - the television cookery series that sucks, slurps, slobbers and screams with a crazy stumblebum style presented as a fast-paced bizarre recipes do-this-yourself-at-home cookery show.
The people featured 'cooking' were all friends, or friends of friends, of Last Ditch Television who produce the series.
The show included the 'Mystery Chefs', two properly-uniformed cooks with plastic masks who just did something strange/comedic for about ten seconds then went away again, in true TISWAS style. One of the Mystery Chefs called Andy, the regular host, who was one of the producers.
