Be a dear to your rear.
Don’t make your hiney whiney.
Nope, that does not go there.
Keep the Hershey Highway pot hole free.
Don’t be cruel to your mule.
Seriously, keep the junk out of your trunk.
Don’t be crass to your ass.
Don’t make your bum glum.
Keep the corn out of that hole.
Don’t get fruity with the booty.
No parking in rear; violators will be ticketed and towed.
Don’t be an asshole to your asshole.
Keep your ass whole.
Winner: Don’t be heinous to your anus.
