Gotta say, I was one of the ones who was giggling uncontrollably over por Sam the garbage man. It was one of those delayed reaction deals that had me sporfling at odd moments well after I'd read the comic and gone on to other things. I was afraid my co-workers would be wondering what was wrong with me.
Speaking of weird exclamations, my pet "swear word" for a while was "Mary Sue MacGuffin!" which I suppose is a pretty vile phrase if you're a writer. It does roll nicely off the tongue, though.
