Wuh-wuh-wuh-one.
One Brazillion.
At least two, but they have to be pretty small to fit.
A: Three - one to change it, one to not-change it and one to both change-and not-change it.
Two. One to screw it in and one to take credit for it.
One hundred and one. Two to wash it, one to dry it, and ninety eight to talk about how dirty it was.
100. 1 to actually clean the shower, and 99 to stand around and talk about how filthy it is.
