Sken-ECK-tad-ee. Nobody is EVER going to figure out how to turn it into Hell by changing one letter, and nobody is ever going to get it to rhyme comfortably with anything in an amusing, piss-taking pome.

Consider:

Hull is dull, Orillia is sillia
Could say Milton-Keynes was built on beans, but willia?
To write a poem, it's heck to be
Looking for a rhyme for Schenectady

Steve, just try to get "Milton Keynes" on a tattoo!
