QUOTE: Sung by Eric Idle in Monty Python. The Meaning of Life (1983): ' Isn't it awfully nice to have a penis / Isn't it frightfully good to have it on / It's swell to have a stiffy / It's divine to own a dick / From the tiniest little tadger to the world's biggest prick / So, three cheers for your Willy or John Thomas / Hooray for your one-eyed trouser snake / Your piece of pork, your wife's best friend, your passing or your cock / You can wrap it up in ribbons, you can stuff it in your sock / But don't take it out in public or they'll stick you in the dock and you won't come back.'
