<human>: Ok reddit,  

I work in a gym as a receptionist--my duties quite often include tidying up the place as well. The guys keep the place clean *enough* to where I'm not picking up mouth guards and jockstraps on the daily, but there's one thing--**PISS**.

A lot of them have the tendency to use the restroom (#1) and completely forget the whole 'flushing the toilet' step. Now, that wouldn't necessarily be such a big deal--save water, free the whales...whatev. But this whole, 'If it's yellow, let it mellow' thing causes a *slight* problem. After they 'let it mellow' for a few hours (I usually don't get in to work until the afternoon)...**The air REEKS of PISS**. I don't know if they're immune to the smell of urine...if they *enjoy* the smell of their own musk...I don't know. 

I've made some signs to address various problems before (passive-aggressive I know, but fuck you)--they haven't been very witty, just something I usually come up with on the fly. **But basically, I'm asking for your guys' help on a 'Flush The Fucking Toilet' sign.**

Now, there are some limitations--it can't be vulgar (we have a priest, and a few younger kids that come here every once in awhile). But, it can be funny, sarcastic, witty--**anything to get them to flush!** We have a lot of college guys in here, so if it can make them laugh a little...all the better.

I plan on hanging some posters in the men's restroom either tonight, or tomorrow morning.

Give me a shortened version of the text
<bot>: The guys in my gym won't flush the toilet, so the whole place smells like PISS. Reddit, make them fucking flush!
