Both Alex and David were interviewed by the Pittsburgh Post-Gazette for an Aug. 17 story about Alex’s appearance on Daniel Tiger’s Neighborhood, his work with the USPS, and their family. While Daniel Tiger’s Neighborhood is an animated series, Alex appeared in a live-action segment in Wednesday’s episode as a mail carrier who makes sure a young girl’s care package gets delivered to her friend. Chris Loggins, the show’s supervising producer, said that the 39-year-old was cast to show “a serendipitous case of life imitating art.” RELATED: See Robin Williams’ Three Kids Now. According to the interview, Alex moved to Los Angeles and wanted to become an actor. He appeared in a few independent films, but later moved back to Pittsburgh where he met his fiancée. He now has a stepson and a one-year-old son of his own named Ashton. He looked for civil service jobs and ended up with USPS. “You’re kidding!” David said was his reaction to finding out his son’s new job. “How ironic he would be a delivery slash postman, and I’ve been pretending to be one for over 40 years!“ae0fcc31ae342fd3a1346ebb1f342fcb CBS Pittsburgh reports that Alex’s postal route is even in the same neighborhood where Fred and Joanne Rogers lived. (Fred died in 2003. Joanne passed away in January of this year.) Alex told the Pittsburgh Post-Gazette that he agreed to appear on Daniel Tiger’s Neighborhood because it is “definitely important to carry on the legacy of what Mister Rogers created.” He also saw it as a way of honoring his dad, who he called the “greatest teacher for me and every other kid that grew up with the show.” And David’s days as Mr. McFeely aren’t all over, either. According to People, he still makes occasional public appearances in character. For more celebrity news delivered right to your inbox, sign up for our daily newsletter. David wasn’t only an actor on Mister Rogers Neighborhood, he was also first a production assistant and later the Director of Public Relations for Fred Rogers Productions. So, it’s no surprise that Alex was around the set quite a bit. “When you’re living around it, you don’t realize how special and kind of cool it is,” Alex told the Pittsburgh Post-Gazette. The paper also noted that David and Fred were personally close and that Fred was the first visitor he and his wife had in the hospital, each time she gave birth to one of their children. In addition to Alex, David and his wife, Nan, have two other children, Catherine and Taylor. Alex’s son is a little young to understand Mister Rogers or Daniel Tiger yet, but he’s started to check out some episodes. “I’m so proud of him and his family,” David said of his son. “He’s such a wonderful dad. It does my heart good to go over there and see Alex taking such an interest in his son … Fred would be so delighted to know that too, because that’s exactly what Fred was doing with the program: encouraging family communication.” RELATED: How Old 100 Iconic Stars Would Be If They Were Alive Today.
