where you describe your bizarre situation and we guess what put you there

This one happened last week. I'm standing in front of a room full of people, probably about 100, when suddenly the sound system in the room kicks on and we hear the sound of pissing. I have to pretend like I didn't hear anything.

I'm not sure how long we're supposed to wait before we share the story, so I guess I'll wait 24 hours, or if someone guesses it I'll respond
