Be careful with this joke, it might trigger some folks.
On another note, I absolutely HATE that our bathrooms at work are single "stall" bathrooms. Meaning, only one person can use the bathroom at once. So when someone blows the bathroom up, and I then walk in to pee, as I'm leaving I have to worry about the next person waiting to use the bathroom thinking, "Damn he blew the bathroom up." -
So what I've been doing is putting the toilet seat up to show that I didn't take a #2 just now to protect myself.
