He and his son participated in a father-son wheelbarrow race at the Springfield Retirement Castle
- His son, Hans, claimed in one episode to be in his early thirties, with an earlier episode, Selma's Choice, confirming it by listing his driver's license as his being born on August 2, 1961 (the episode aired on January 23, 1993). His son, however, according to a flashback, was mayor of Springfield 30 years ago, which would indicate that he is at least 60. Therefore, it is possible that the mayor was not his son, but rather himself, given the resemblance between the two men. This would suggest that he, like his son is also named Hans.
