The way I always learned it (in Louisville, Kentucky) goes something like this: ♫Great Green Gobs of Greasy Grimy Gopher Guts Rolling Down the Bloody Street, Mutiliated Monkey Feet French-Fried Eyeballs, Dipped in Kerosene And me without a Spoon. ♫ But I still have a straw! SLLLLUUUUURP!
But I also factored in the possible variants of ♫Itty-Bitty Birdie Feet♫ (in lieu of the monkey's) and ♫Octo-Pus Tentacles♫ in place of the eyeballs. Enjoy!
