I also like the old Castle Thunder sound effect: The sound effects on 'Rocky and Bullwinkle' are also fun too. I've always liked the old Hanna-Barbera sound effects best, along with several of the classic WB sound effects. It was omitted in season 1, but for the last 3, it was an unnecessary addition, after the second animation studio practically took away other good aspects of the superior first season. My least favorite sound effect was in the original Spider-Man series in the late 1960's when that annoying zip noise was made whenever he swung across the screen. The sound effect added a couple of bings, bangs, and boinks at about the point it would freeze on Fred Flintstone. That last time it was used was for one of HB's final logos, the rectangle that had stars from several series including Flintstones, Jetsons, Yogi Bear, Huck Hound, El Kabong, and Scooby-Doo dashing all over the screen.
This would be later used whenever Winsome Witch used her magic (remember her catch phrase Ippity-Pippity-POW!!!), among other series. Of particular note would be the sound effect that's first heard when Jet Screamer makes his spin entry on The Jetsons. I pretty much liked the majority of HB sound effects, since they were used in a lot of series.
