pacaderm??????

Was the Pacedrem ever on an eposide or just talk about with the pizza story?

Pachyderm has never appeared on the show. It surprises me that he hasn't been brought on.

I thought he was the guy who "took IT out" for Elaine.

No, the guy who took it out was named Phil Tatella. He did this while Elaine was relating the anecdote about pachyderm juggling the pizzas.
