I would probably say "I knew it!" Then die

Die on my feet fully dressed instead of on the toilet with my pants down, basically.

I'd like to know where the subliminal fear of something being behind the shower curtain came from. Seeing as how all of our distinctive fears are fueled by something that happend long ago in the human race.

Strike with the toilet brush, then run.. come on... if you're going to spend that much time obsessing about stuff that will never happen, you start planning for it.

"murdereres"

Im not paranoid or anything but I would take out the bathroom scale and eother a. chuck it at him/her or b. bash their face in with it

Run like hell and hope they get caught up in the shower curtain.

Grab the shampoo and squirt it into his/her eyes, because that stuff hurts! Then I'll try and take them out first.

in the words of plankton, "I don't know, I didn't think I'd get this far"

Die

Murder the murderer

Shit on them

Run. Or try at least.

Die knowing I was right

I just check behind the curtain to make sure there's no one hiding behind it. I've had someone do that and they jumped out and took a picture of me while I was peeing.

Smother them with the curtain!!!!

For me its not a murderer behind the shower curtain. It's closing my eyes and a graboid busting through the drain.

Hence the glock
