In how many episodes of Seinfeld has Larry David appeared?
 

Not counting his voice - only his appearances.

0??

I know it's at least 2.

Looks like 3.

Is Anybody A Marine Biologist?

He was visible in that one.

Ok, thanks. But now another question... About half the sites I read state that Superman was visible (or referenced) in every single Seinfeld episode, while half say this just isn't true. Does anyone know for sure whether or not Superman was either visible or referenced in every episode?

From what I remember, it was most episodes, but not every. I think that there was a picture on his fridge or in his apartment, so most kitchen scenes had Superman in the background.

He had a statue on the shelf next to the desk in his apt.

i heard there is some sort of superman item/reference in every episode (whether it be the statue or anything else).

I've heard the same, but I don't believe it. I don't believe there is a reference in either "The Parking Garage" or "The Chinese Restaurant," to name two.

The following article kind of examines and debunks the story:

Yes, me thinking of these 2 episodes is really what prompted my question.

Stretching credulity!
 

01 - Good News, Bad News
Jerry wears clothes the same color as Superman's uniforms.
When Jerry sits down to watch TV, he is wearing a bright blue pair of sweatpants, and a bright red sweatshirt.

This is a bit of a stretch if you ask me.

He'd have to have red underpants on over his sweats to make it legit.
