I want this so bad but the only door in my apartment other than the front door is the bathroom door. Are you telling me we have to play through someone urinating? Sure, I could stop playing when someone used the restroom, but I think I'd be too tempted to get a deuce while dropping a deuce. Technically I think a deuce is a tennis term, but ping pong might as well be called tiny tennis. It has the same musical ring to it.
This is the type of home addition I'd need to just install instead of going through the proper channels. The proper channels would be my landlord and girlfriend. I'd get a big no from both of them. For my girlfriend, I already have too big of a problem leaving the restroom door open. For my landlord, he's more of a billiards guy.
