This is the place to dump all your witty palindromes, anagrams etc.
Just to get the thread going:
Marcus Edward Trescothick: I scored a duck? Screw that, Mr!
Vanilla Pepsi: Nipple Saliva
Mother-in-Law: Woman Hitler
Marc Robbins: Man Robs Crib
And some palindromes:
Step on no pets.
Rise to vote, sir!
Ed, I spotted a clam in an animal cadet topside.
Of course, feel free to contribute any other types of wordplay.
