Not sure why but was thinking about some of the daft things they used to do in MBUK years ago, some of the best that I can remember are
Trying (and failing) to cycle accross The Channel wearing scuba kit
Cycling with the RAF mtb club and being blown off their bikes by the downdraft of a Wessex
Riding a wall of death
Attaching a parachute to handlebars and being blown uphill
Would love to see these online somewhere!
