I have to go to the bathroom but the water is turned off due to a plumbing problem! Help!?

I really have to go to the bathroom (#2) but we have a pluming problem so the water is turned off so I can't flush and it would stink up the house if I didn't flush. What can I do?I go to dance in an hour and there's a bathroom there but I don't think I can wait that long! I can't go to somebody elses house! Thanks in advance! -Kelley
