I don't think I've seen this one. Normally there's some sort of interaction with the audience.. like waving "bye bye.." attempting to make an ad hoc umbrella.. SOMETHING to make the accident and ensuing fall and splat hilarious. This is 50 seconds of pure terror in his eyes.
This is one of the best Coyote and Roadrunner bits. The look on his face as he pushes the top boulder away from the bottom one mid-descent is a wonderful mix of resignation to his current failure and knowingly-futile attempt to avoid the resulting pain.
