You Can't Do That On Television is a Canadian television programme from the 1980s, best remembered as that show with child actors and gross-out slapstick sketches that usually involved the stars being covered in slime or water, or being pelted with cream pies. I remember this one best from the late 1980s, when in Australia, the ABC used to show reruns as part of their line-up on The Afternoon Show. I've picked this clip because we see a lot of one of my favourite characters from the series, Moose, in these sketches.
PS Random Trivia. Alanis Morrisette starred in a few episodes of the series while in her teens.
