All I can see is the Santa scene in "A Christmas Story" running through my head. Only now pull that image into the police department with a polygraph!

A mall Santa at the Brent Cross Shopping Center in London is giving out lie detector tests all this week to find out if they're actually naughty or nice. Santa's magic is no longer relevant I guess!

Kids who go to the mall will be hit with questions like, "Have you been good this year?" and, "Do you always clean your bedroom?" Then Mommy and Daddy will get the results of the test. If it isn't scary enough to some kids to sit on Santa's lap! Never fails you always see a kid or two freaking out on Santa. Now they have to be hooked up to a machine and interrogated!

The mall says they're doing it to, quote, "instill a sense of honesty among children."
