We've all gotten tired of the "fry/Happy Meal" bit - and who wouldn't appreciate (or has ever even heard) a good Slinky joke? Not this guy.
This saying has legs and stands on its own. Anything more that I write might actually knock the shine off this gem.
OK, that's funny. I can say that because I didn't come up with it. But I will tell you - it's even funnier when you envision a buzzard cringing and falling off a truck of, well, poop. See also Scatological.
** NOTE: The 's' on neckbones is purely optional.
I live in SC, and even I've only heard this one a few times. But it's a keeper. Some folks apparently cook pork neck bones. Wash 'em up, throw 'em in a pot. After that it's anyone's guess. Used thusly: "You ready to bolt? Then it's on like a pot of neck bone!" See also Redneck.
A stellar variation on the "football bat."
Used as such: a buddy uses a really janky pickup line on a girl and gets shot down; you seize the opportunity by saying, "Man that was as smooth as a stucco bathtub!"
If this doesn't make sense, I can't help you.
"Red wire? Snip the red wire? Is that the one on the left? What? To the left of the blue? What blue? Oh hell. We're screwed."
