A Silly Specification Experiment

As an antidote to the February blahs, here's a fun little writing experiment I hope you all might help me out with.

Step 1: Watch the extremely goofy 10-second video below.

Step 2:
Without looking at any of the comments on this post, write a sentence describing what happens in the video. You may rewatch the video if you like.

Step 3: Post your own sentence in the comments.

The hypothesis and rationale for this experiment will be given at a near-future date; in the meantime, rest assured there are no wrong answers here. And thank you to all who participate!
