TV Guide just put out a list of it's top 50 worst shows of all time. And "Hello, Larry" was named #12! I think I've seen this show once or twice MANY years ago. I don't really remember any specific episodes, but if it was even HALF as bad as the "Hello Larry" / "Diff'rent Strokes" crossover episodes were, I can see why it made the list. These were some of the worst episodes of Diff'rent Strokes ever. For the most part, I agree with the TV Guide list. But I really wish they would have included that cheesy 80s sitcom about that girl robot, titled "Small Wonder." To this day, I think that is the worst show I have ever seen.

I was really surpriced that Hello Larry made that list because I didn't even know it was that well known.
I've got 2 episodes of it on video and 1 of them is really funny, the other one isn't great but is still funny, so I'm not sure why it is so unpopuler.

I also thought all the DS crossovers were great too, I think Larry's character along with Ruthie, Dianne and Morgan are all funny.
