Even though he doesn't appear, there's also an entire episode of "Growing Pains" that is centered around his upcoming presence at a charity auction held at the Seaver's house. They stress over looking their best, and how he's going to land in his helicopter. In the end, they never get to see him, but he leaves a hefty donation for the inner city community youth center that's being built in NYC. There's also a line about how he enjoyed the common snacks served at the event.
