The Adventures of Buckaroo Banzai Across the 8th Dimension (commonly just called Buckaroo Banzai) is one of the most totally awesome strange weird crazy sci fi freak movies of all time. I highly recommend watching it at least once a year, whether you really need it or not. Plus it has a really hooky and memorable theme song.
What I'm listening to right now.
"End Title Credits Music to Buckaroo Banzai."
And these days, who can think about Buckaroo Banzai and not think about [broken link! FIXME] Genki Sudo, and listen to some song of his a few times around?
