The VERY creepy logo for "Starry Night Productions" (1984-1989). This is the vanity logo for "Night Court" producer Reinhold Weege. It was dropped in 1989 when he left the series.
Fun Fact - the crazy laugh is rumored to be that of Mel Blanc. It was not used in the first season.
I've never been a fan of the piano chord (sounds like GOOM!). And the laugh? Whoah, that is some freaky stuff!
The Warner Bros. logo is the current logo. The shield was always seen at the end of this program, but this is the current variation, with the website address at the bottom.
