never seen again?

Are there any episodes that have never been shown in syndication?

I believe that with the exception of the current season, all episodes have been shown. However, it's an interesting question, as some shows do withhold certain episodes from syndication; 3 or 4 Twilight Zone episodes were left out of syndication for the first 20 or so years of the syndication run, the reason for 1 or 2 being litigation over the true authorship of the script and the reason for a couple of others being that they were deemed offensive to particular ethnicities. (Which seems interesting, although having nothing to do with Seinfeld.)

yet, like "Yadda-Yadda" or the final one with George becoming paralyzed. There may be some sort of mandatory waiting period between when they are last aired and when they can be shown in syndication, because the first half has been shown, and a couple of shows have even been on twice now.
