John Carpenter's Dark Star ends with an astronaut surfing in space as country music plays, so yes, I think that counts as wacky. For those who haven't seen it, Dark Star is a low-budget 1974 sci-fi comedy about blue collar workers in a spaceship, and sorry for spoiling the ending just now. It's also the blueprint for Ridley Scott's Alien, and not because the plots are kinda similar -- it's because the writer of both movies, Dan O'Bannon, straight up said Alien was "Dark Star as a horror movie instead of a comedy."
In fact, there's even an early version of the monster from Alien in Dark Star. Here it is:
It went from a ball to a phallus, but then again, didn't we all at some point?
If that looks like a beach ball with claws, that's because that's literally what it is. A beach ball, two claws, and some glue were the only special effects Dark Star's budget could afford for the space monster who hides in the ship in the second act of the movie. O'Bannon and his writing partner Ronald Shusett later took that second act (and the whole thing about the blue collar workers stuck in space for a long time and occasionally being cryogenically frozen) and expanded it into a full script, also using ideas from an earlier story O'Bannon had written about gremlins causing shenanigans in a World War II plane.
