Interesting,I have had four parties at my house and all have resulted in me having to unblock the drains with drain rods whilst the party is going on. Is it the freedom of having free toilet paper that people go crazy with it.
Reminds me of a Caravan site I once visited which had the toilet roll chained to the wall and a notice saying
"PLEASE USE THE TOILET PAPER ONE LEAF AT A TIME"
