Cool, once I got to Disc Four, I watched that same clip as an Easter Egg on my considerably larger TV screen, so it was even better.
Although, I found another clip on YouTube entitled "Baby Actor Has a Meltdown" which isn't one of the listed 'Dino-Eggs' on the DVD sets. BUT, a couple of quick clips from it are used in the Easter Egg we were just discussing, so it almost made it.

The part used in the montage is where Baby's head spins around backwards. Kevin Clash was doing it off-camera for fun at the time, though the same gag was used for a scene in the 'Terrible Twos' episode during a hilarious parody/homage of the Exorcist.
