Discussed before. Someone even added a cute little rhyme to remember how to spell (hit Ctrl v) Woolloomooloo. Matters little, I forget, but I have the real thing here.
This one is much better and easy to remember. Sheep on the toilet. Cow on the toilet. Wool loo moo loo. How to spell Ctrl v Woolloomooloo, sheep and cow toilet. I won't forget that now. You won't either.
