I know of some older people that have matches in their loos to strike after youve been for a.. erm sit down..Suppose its a similar priciple to a candle with the same effect. Or KABOOM??
Matches in the toilet ... you burn away the access methane as well as the smell of sulphur and phosphate being more smelly than that of methane and other bowel smells.

One of life mysteries, like plastic collars on new shirts.. or women!
