I just watched Back to the Beach for the first time in a long time and forgot how good this movie is! For fans of classic tv there are a bunch of cameos my favorite being Jerry, Tony and Barbara's towards the end of the film. Jerry and Tony play Siskel & Ebert type judges and Barbara is an announcer for the surf competition. If you liked The Brady Bunch movies it's in the same vein as those. Frankie Avalon and Annette Funicello star and spoof their old beach movies.

Here's the clip of their cameo.

Yep, he finally had to get a new one!

The guy who posted that video, Scott Hettrick, has posted every Still the Beaver/New Leave It To Beaver episode on Youtube. At least, I assume they're still there, unless someone has made a copyright claim.
