Would have been when his belly (pillow) fell out from under his oversized coat.
Might have been his lack of cheer.
Probably was the sound of his voice when he was asked to start the race.
His darker hair poking out from under his wig.
Santa kneeling at the finish line because his legs were tired.
Where are his reindeer?
His helper (me…mom) speaking firmly to him through a fake clinched smile to do one of the following: Smile for the picture! Stand up! Look Happy! Shake their hand! Be nice! Tie your shoe.
There were more, but I think it is safe to say that being Santa takes a lot more work than just wearing a suite…even if it fit.
