Well, I didn't do this but my friend did:

I have a tiny ant problem in my apartment so I went out and bought some RAID, zapped the bastards, and stuck the rest of the bottle in the closet. A night of partying ensues. I wake up the next morning, the bottle of RAID is in the middle of the living room floor and it's empty. Hmm.. I only used it once, why the hell is it empty?

Apparently, my drunken friend thought it was spray paint and decided to "spray paint" my fence. Fucking jerkoff.
