I'll show you the actual IMDb “Known For” image in a second, but it's tougher these days to cut out the character names that might give it away. So for now I'll just list off the productions this actor, per IMDb's algorithm, is KNOWN FOR.

In this order:

1. The Waterboy
2. Night Shift
3. Click
4. Arrested Development

I knew he was in 2). I also knew he was in 4) but he's not the first name I associate with that great show. I did not know he was in 1) and 3), but then I'm not a huge Adam Sandler guy. Maybe that puts me at odds with the culture and IMDb's algorithm. If the algorithm truly taps into the culture. Which I doubt.

The point is, there's a massive #1 that IMDb's algorithm is somehow missing. It's older than these others but it was seismic. And it's still part of the culture—particularly as a recent catch-phrase. And if you're like “Forget it, old is old,” and you want a recency bias, there's a current, critically acclaimed show for which this actor has won an Emmy. The algorithm supposedly cares about that.

More clues? He was one of the most famous faces of the 1970s for playing this character on this TV show. He wound up starring in movies as a result. But he's mostly known for TV. For this missing TV show.

Hell, when he's introduced, people often place this character's name between the actor's first and last name: X “Y” Z. The character is referenced in “Pulp Fiction” and Adam Sandler's “Hanukkah Song.” There's a statue of him, as this character, in Milwaukee.

Want more? Ayyyyyy.

Exactamundo. It's Henry “The Fonz” Winkler, who, on IMDb, is somehow not known for playing the Fonz on “Happy Days.”

I think IMDb's jumped the shark.

ADDENDUM: August 2024: Just came across this on Henry Winkler's IMDb page:

If your website is telling you a guy is known for a thing, and your “Known For” algorithm doesn't include that thing, you might want to doublecheck the algorithm.
