So you guys went to all the trouble to find a couple of berets, but you couldn't get a sufficient amount of painting supplies? I think maybe your priorities are a little off.
For some reason, Ernie is suddenly right-handed in this sketch, and I don't know why, and not knowing is driving me a little crazy. My best guess is that they wanted the paintbrush in the hand nearest the camera when he started painting on the canvas, but there's no way to know for sure.
Right at the end when Bert says, "Oh, that's terrific!" he sounds a lot like Fozzie Bear.
