I wasnt aware they were so ubiquitous.
"The toilet trap is a simple electrical trap designed to shock anyone who decides to use the toilet, and can be disarmed by standing on the bowl of the toilet and removing the http://fallout.wikia.com/wiki/Microfusion_cell_%28Fallout_3%29 from the tank. 35 microfusion cells are in the tank which provide the charge, and are added to the player's inventory if the trap is disarmed...One example of this trap is found in the http://fallout.wikia.com/wiki/Tenleytown/Friendship_station's bathroom nearest the http://fallout.wikia.com/wiki/Chevy_Chase_North exit. A skeleton lying near the bowl serves to warn the player of the danger. Others can be found in the http://fallout.wikia.com/wiki/Robot_Repair_Center, http://fallout.wikia.com/wiki/The_National_Archives, the http://fallout.wikia.com/wiki/Museum_of_Technology, and in the http://fallout.wikia.com/wiki/Statesman_Hotel."
I think they should just duct tape a mine to the back of the doors. It should fall to the ground when opened giving you precious little time to disarm if you didnt peak over or under the door first.
Are you the fun police? While they arent critical to the game they provide a bit of humor and an oddity to discover. That doesnt hurt anybody...except whoever unwittingly used the toilet.
