once when i was a kid and up to no good we were in this dudes house while he// wasn't home, and found his bowl and snatched it. Was a homemade peice he must have been using for years cause we couldn't pull a hit off of it at all, totally clogged. The mouth piece was a plastic tube, we ended up cutting the tube down the middle and ended up with a solid tube of resin several inches long, was pretty nutz. tasted like ass but we I soo much of it hah
