On Superbowl Sunday, I had Mom over for dinner. She's a Packer fan, and since they washed out the week before, she had no interest in the game. We kept it on in the background in hopes of catching a funny commercial. No luck, they were all crappy. But we did see McDonald's "Pay With Lovin' " commercial, which struck a chord because we are a "No Public Displays of Affection" family of the first order. We had a giggle fit discussing what we'd do if we were given that challenge. I don't eat at McDo
