This video is too cool not to post. Every commenter who knows why this happens, and can explain it, gets a cookie*.
If no one chimes in, and you’re curious about how this works, let me know and I’ll explain it in a future post.
UPDATE: Man, you folks are smart. You all get cookies. Well, all of you except mmf, whose dogs get the cookies.
*Said cookie will be made entirely by yourself at your own expense, but you still get it.
