Cat Willy

will unclog a toilet and clean up cat-puke 

One of the "prime" features that any sensible-minded gal --- especially one with one or more furry feline companions --- secretly jopes to see in a guy's "about me" details when perusing the personals ads.

Ladies, if a dude whom you're dating treats you respectfully and is a cheerful-natured helper and therefore "will unclog a toilet and clean up cat-puke" without grumbling or without even being asked to do it, hang onto him for dear life --- he's d-e-f-i-n-i-t-e-l-y a "keeper", hands down!
