High Diving Hare (1949)
"Due to an unfortunate delay," announces the barker, Bugs Bunny, "Fearless Freep will be unable to perform his high-diving act today." But Yosemite Sam had bought out the house just to see Freep. If Freep isn't going to dive, someone else will just have to. And that someone is going to be Bugs Bunny. Bugs is no high diver; but at gunpoint, he'll have to take his first-ever 500-ft. jump into a tank of water. Or will he? Yosemite Sam will find himself tricked into doing the dive himself - many times - before realizing that no matter what he does, Bugs's blissful ignorance of physics will always save him.
