Chris often jumps in and tells folks "he's only kidding".
One of my favorites used to be when I dressed up like a penguin and attended corporate events. We'd sneak out early, but often someone would spot us and ask "why are you leaving?". With a straight face, I'd point at Chris and say "this is my rent-a-date and, if I don't get her home by midnight, she'll turn into a pumpkin". Their facial expressions and eyes were funny to observe and, before they figured out that the Cinderella story didn't end that way, we'd make a hasty retreat.
