Okay, couldn't resist passing on a few old saws from the frozen north.
"Big enough to burn deisel and pull a pup" Describing a mountain of a man or woman.
"Not too thin where the pin goes in" A less than flattering description of a broad beamed woman.
"Wild 'n' wooly 'n' full of fleas...never been curried below the knees" I know there's more to this one, but I can never remember it all...describes a head's up kind of cayuse (and sometimes rather rambunctious children).
"Dumber than a sackful of hammers" Which really is about the most illogical description for low intellect still floating around out there.
In the same vein:
"Not the brightest bulb in the pack"
"Not the sharpest knife in the drawer"
"The lights are on, but no one's home"
On another note:
"Fell out of the ugly tree and hit every branch on the way down" Another pearl describing the less the beautiful.
Hmmm...kind of tired tonight...let's see... oh, yeah:
"Hornier than a two-peckered billy goat" (sorry kids...don't ask your mom to explain it, okay?) Describing randy individuals..especially loggers or oilmen headed home after a long stint in the bush (for a long stint in the..never mind).
And finally...
"A snowball's chance in H E double L" Basically describing pretty poor odds.
Take care.
