The up's and down's of having Tenants

As many people already know, we rent the 1st floor of our three story house to who ever needs a room. We currently have all three rooms filled and if all go's well we can make about $400 per week. More recently NOBODY has been paying rent, so my parent's are going to take the appropriate legal actions.

One tenant (who shall remain nameless to preserve his dignity) has been "MIA" for quite sometime (Or Missing In Action for those that don't know). So my mom comes up to me and say's "I think the dude skipped town, break into his room for me."

So i obviously want to kick the door down but can't because my mom doesn't want me to break anything. The next best thing was to cut the lock in half, which i didn't protest to, GO POWER TOOLS!.

When we get into the room, a hurricane of "stank" flew through the rest of the apartment, at that point my mother, and sister RAN for the front door.
Upon further inspection there were STACKS of cans filled with urine. THE GUY PISSED IN CANS FOR PETE'S SAKE.

I proceeded to go outside and gag over the rail on my porch. one of the other tenant's said that this had been going on for quite sometime. And now we have to find someway to clear the GALLONS of piss out of my house.
