Good for a quick chuckle.....

In an episode of "Newhart," Dick and Michael attend a convention at which they hope to sell Dick's local TV show into national syndication.

As the scene opens, we can see for a few seconds one of the other booths plugging another potential show for sale. (See pic...)

Small image (from the best quality vid I could find online), but hopefully legible.

Heh. I actually did a full-series re-watch of Newhart early this year and I missed noticing that. Good catch.
