Page "The Santa Clause" Paragraph 5

Soon, however, Scott starts gaining weight and his boss, Mr. Whittle ( Peter Boyle ), likens him to the Pillsbury Doughboy and he interjects a presentation on the company's new toy by complaining about Santa not being represented with his sleigh and they should simplify their toy designs.

He develops a ravenous taste for Christmas treats, like cookies and hot cocoa.

Scott's facial hair grows practically overnight, and shaving it off has no effect as it regrows instantly.

His hair turns gray then white, despite all attempts to dye it.

He somehow knows who has been " naughty " and " nice ".

Scott also starts wearing clothes with red and green, and his heart even beats Jingle Bells.

Children ( who somehow know he is Santa despite Scott not dressing like him ) approach him with gift requests.

His rapid transformation worries his ex-wife Laura ( Wendy Crewson ) and her new husband, psychiatrist Dr. Neil Miller ( Judge Reinhold ), who tries to terminate his visitation rights to Charlie.

They question his mental stability, and believe that his changes are attempts at getting his son to like him.
