The sign reads
"Please Leave This Toilet As You Would Wish To Find It"
So I'm thinking
I would wish to find it...

Fitted with a massive magical machine able to dispense any flavour of jelly bean I could imagine in a split second...

Smelling of the sweetest most delicate fragrance in the universe (the yaroooz flower from the remote planet Baluha)...

Covered in hundreds of priceless rubies, emeralds, sapphires and diamonds, each one larger than a giant's thumbprint...

Surrounded by sparkling soft sand from a beautiful beach on a unknown Pacific island

As I can't provide any of these things
When I'm done
I'll brush
Air freshen
Gently lower the seat for the ladies
Then quietly depart...
