bung in some brick acid. 'they cant take it up em'

[Grimly Curmudgeon]

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Andy Dingley saying something like:

I'd bin it on sheer colour alone, but I suppose your bum doesn't care.

The acid only works effectively up to the normal waterline, but much of the scale on the rear U-bend builds up above the water level due to the repeated cycles of wetting and evaporation. That reference to stalactites and stalagmites wasn't entirely fanciful.

[The Natural Philosopher]

then bung up the exhaust pipe and fill er up, Cap'n Mannering!

[Ian White]

No... that won't work (clues are in the words "U-bend", "bubble" and "CO2").

For true understanding, you must kneel an hour before the other man's toilet bowl.
