One Sheet Wonder

You sit on the can, unleashing a massive load only to realise you have but a single sheet left clinging to the roll. This triggers your one sheet adrenaline, allowing you to use this last sheet with such efficiency that you still manage to get the job done, thus a one sheet wonder.

A trip to bathroom require the use of only one wipe; which, although may be a sign of not having enough fiber in one's diet, it is definitely a wonderful thing.
