Mall Santas Are Clearly Field Agents

I’m teaching a class of five- and six-year-old children, and, it being close to Christmas, a debate has somehow erupted about whether or not there is a Santa Claus. The class is clearly split into two camps, one for and one against the jolly old man being real. Then, a kid from the True Believer camp drops this bombshell:

Kid: “Oh, yeah? Well, if Santa isn’t real, how come I saw him at the mall on the weekend?”

Best. Fallacy. Ever.
