Life can be full of coincidences. Some of them are fun and some of them are just plain eerie. Such is the case with Karl Swenson. This particular coincidence was so odd that I think it is fair to say that it haunted the cast of Little House for months after it occurred. Karl is best known for his performance as the kindly Lars Hanson in NBC's Little House on the Prairie. He appeared in forty episodes of the show from 1974\u20131978 as Walnut Grove\u2019s founder, a kindly man named Lars Hanson played to perfection by Karl Swenson. Of course, we remember Karl on TV and in movies many times over the years. He\u2019d played Eddie Haskell\u2019s dad George in a couple of episodes of Leave it to Beaver and made the rounds on many TV westerns like Bonanza, Gunsmoke, and I believe this image is from one of my father\u2019s favorite programs, Maverick. In the '60s, Karl even showed up in another one of my favorite shows, Hogan\u2019s Heroes. Of course, I didn\u2019t see any of these appearances until the '70s when reruns of shows like Leave it to Beaver and Hogan\u2019s Heroes played in the afternoons. He was also Opie's friend, Mr. McBeeVee on The Andy Griffith Show. RELATED: Michael Landon, America\u2019s Favorite Pa, Had A Truly Troubled Life However, it was on Little House that Swenson really found a home. Over the course of the show\u2019s first five seasons, Swenson made 40 appearances as the founding father of Walnut Grove.\u00a0 And it was during the fifth season where this very odd, very strange coincidence occurs. It takes place while the cast and crew were filming an episode titled "There\u2019s No Place Like Home." In this episode, the Ingalls family along with other former Walnut Grove citizens return to town after an extended absence only to discover that the town is dying. And along with the town, Lars Hanson is very ill as well. While the episode is about a rebirth of sorts for Walnut Creek\u2026things don\u2019t go as well for the town\u2019s founder. And, as the episode comes to an end, we hear Laura Ingalls tell us that Lars passed away.\u00a0 Definitely a sad story, but there really isn\u2019t anything strange about this story up to this point. Here\u2019s where things get a little bit odd. You see, it wasn\u2019t the intent of Landon to have Lars die in this episode. However, Karl had pulled Michael aside and talked to him about being ready to retire from the industry. He was ready to be done. Karl was, after all, 70 years old and wanted to focus on other things. As such, the episode was written with the much sadder ending. Then, eight days before the episode aired on television, Karl Swenson had a heart attack and died while visiting relatives. And things even get more strange because according to an article in Peter McDonald\u2019s Hollywood Hotline, Swenson\u2019s moving final performance as Lars Hanson, which had reduced the entire cast to tears, was now causing them to speculate as to whether Karl had some sort of premonition of his own imminent death. Who knows? However, when the episode was broadcast, we have to believe that all of the castmembers felt that Swenson\u2019s performance was a bittersweet and haunting memory of their dear friend. Of course, it would only be a handful of years later that Michael, while on a ski trip in 1991, started to get migraines that were near unbearable. After a visit to the doctor and a host of tests, it was determined that Michael had developed a form of pancreatic cancer that was swift-moving and inoperable. Just months later, Landon would leave us as well. A heavy blow for those of us who were big fans of his work.
