Maybe we could have a toilet with water in the bowl with a sign over the tank that reads, "Free Swirlies!"
Have a 'Champaigne fountain'? Get a bidet and fill it with punch! Put a pump in the tank to flow punch out the water jet in the bottom of the bidet!
Toilets for pit chairs?
I still think a tent with a sign reading " LeMons Theatre", Now Playing, "Two girls and a Cup"! Maybe not really showing any movie, just for show!
Maybe all the above for the website?
Ooooh! A toilet smoker! Cook our burgers on it at the race!!
