Katie Christman's height has been measured over the years next to the same "Wicked" musical poster. It seems to be a popular pose. Some kids get measured against a wall in their home like on a recent episode of 'This is Us,' but not Katie. Her mom says it was unintentional. Each time they go to the show, Katie's photo gets taken in the same spot next to the poster outside the theater. InsideEdition.com's Leigh Scheps (http://twitter.com/LeighTVReporter) has more.
