Um, gosh. I once lived with some guys that stained the carpet (constantly) with bong water and burnt a hole in the carpet drying their weed. Every week when their government money came in they would stock up and we'd wave to them as the walked straight in the front door to their room, heads bent, not seen again till the morning.
Not the same league, but I still wanted to vent. (fyi this was about 15 years ago)
