The Vibrating Bum-faced Goats

The Vibrating Bum-Faced Goats was a—presumably—one-off cartoon from an early nineties edition of the British adult comic Viz. The plot, such as it is, revolves around a farm where the livestock consists of vibrating goats "and every one had a face just like an arse!".

Despite its one-off status and (maybe because of its) ludicrous premise, the strip became infamous and is still occasionally referenced, for instance in the Viz 2008 calendar, which features Edwin Landseer's "Monarch of the Glen" redrawn as a bum-faced stag.
