Oh yeah... Sam. Good old... Sam. Ahh. Okay, I admit, I really didn't think this was a character until I cross-checked with the Comic Curmudgeon and Sam is, indeed, real. He was Margo's party planning assistant, back when she was actually doing weddings, circa 2007 B.C. (Before Carla). He was only in a few strips, but since he was a dude, everyone pretty much assumed he and Margo were going to get together. Now that we know he's thrilled to be in charge of a old rich lady's aspirationally WASP-tacular wedding, we can probably rule out that romantic possibility.
