Tom's Top Tale: Toilet humour

Having just recovered from a 2 hr Broadband 'outage' I wonder whether anyone has yet written in on the unusual toilet topic with mention of the communal system at Cultybraggan Army cadet-force camp in Perthshire?

To wit a row of stalls over an approx 30" diameter glazed pipe with a series of orifices (no wooden or other seats as i recall) one per stall and which functioned as the end nearer the water tank was perhaps a foot higher than that at the other end ....

This was colloquially referred to as 'The Magic Flute' and a reputedly favoured ploy was to be in the uppermost stall when some of the others were 'engaged' and light a wee paper boat just as the flush operated, thus eliciting a series of varied squeaks ,squawks and yelps as the wee burning boat proceeded down the line...
