That is cool! I have thought about doing this before too....I had a principal in junior high school (he was a supreme prick too, back then) but he eventually retired from the school district and became a mall Santa. As a mall Santa, he made a KILLING over the holiday season. Apparently it paid quite well. Like, he'd do the mall Santa thing over the holiday season and then spend the rest of the year golfing in Arizona and Florida...
Couple years back he was riding his Harley up I-5 north, somewhere north of Seattle, near Burlington iirc....lost control and went down on the road, only to be struck by a big van, which killed him...RIP Mr. Higgins...but anyway, he was already quite a plump man with his own beard and it was long and white so he made an excellent Santa (so I hear anyhoo, I never once sat on his lap but I did have detention once or twice)
