In 1984 or 1985, my mom and dad's friend Larry, who was and is a professional broadcast cameraman as well as an avid skydiver, created this fan music video for the Van Halen song "Jump!"
Edited linearly on deck machines, it's pretty great and features some great 80s sunglasses, mustaches, short shorts, hacky sack, and awesome skydiving-while-lip-syncing-to-Van-Halen.
Also of note, Larry actually showed this video to David Lee Roth and the Van Halens backstage, and they loved it.
Enjoy, and remember: you might as well jump.
