Couldnt name one favorite, but some that I would name as favorites have already been mentioned:
Big Wednesday, classic line froms Jacks Mum during the party "Keep waxer off the coffee table" only to see him crush it at end of party getting his toes over.
Strom Riders, love the three stooges like pre movie feature of Kongs Island with Rabbit, Chappy and Kong. plus some awesome early 80's tube riding.
Innermost limits of pure fun, camping and surfing on the airforce base and ducking for cover when planes doing a bombing run.
Anyone remember the Video magazine type movies Hawaii 9-0 and Hawaii 9-1. show casing 1990 and 1991 Hawaii seasons with cool soundtrack like the Angels, INXS etc. I watched them over and over and over as a teenager.
Currently love Sprout especially the bit at the end with Rasta and Dan Molloy on the single fin Lopez guns pulling in to massive barrels in the Mentawais.
The surf vids have been copping a bit of a flogging at home of late while trying to get a 3 week old settled at night!
