Thanks for the ping, SISU. I'd like to offer up a fully legit schenario which could be presented by his defense attorney:
If a guy's sitting on the throne and can't leave it and the air's getting thick and choking, and the only objects within reach are say...a sledgehammer, a claw hammer, and a Vicky's Secrets catalog...he's not going to want to damage his catalog in using it as a weapon, and even when rolled up it won't leave a mark--it just makes noise. That leaves the guy with the other two weapon choices as he sits in wait until his perp roomate has to use the throne.
Never take the last of the TP without replacing it for the next person. (Bad form.) It's just etiquette. ;-)
