I swear... the way women use toilet paper makes the rainforests cry.
Men : Use 2-3 pieces, then put in toilet after usage. Repeat as appropriate.
Women : Grab first piece of toilet paper. Pull as hard as possible, and watch as the roll spins 30+ times. Then use the handfuls of paper to "mop" necessary areas.
End result : Women use -at least- 10 times more toilet paper than men.
I can attest to this personally. When I was living with my gf, we went through several rolls a week. Now I'm living on my own [though we're still together] and I get through one four-pack a month.
