Anyone with a penis entering a ladies room while my daughter is in there(*) won’t have one when they get out.

...and if they go in by mistake, like happens occasionally when in an unfamiliar location, you’re gonna go all psycho on them, too...?

[Tanniker Smith]

Psycho? No, I'd go all Irish on them. (Some friends say it's a fine line.)

"''scuse me, but you want this door over here."

The difference is then either:

oh, my mistake, thanks. (No prob.) or

but I'm a girl. (You're gonna be.)
