Reading the Wiseacres thread reminded me of my favorite lines, the ones that really did make me laugh out loud. So far, my contenders are:
Boris B, for his observation that “if you have a dog, don’t name it bear. But if you have a bear, by all means name it dog to even things out a bit”
And Ukelele Ike, for:
“Oh, I don’t know; we had five Barksdales in our Kindergarten class.”
(I’m sorry these aren’t verbatim quotes; I tried to use the search engine but-surprisingly!-didn’t locate the actual threads.)
