Vintage Sesame Street clips

jtemperance linked to a classic Sesame Street bit on YouTube, funky shapes dude. Which led me to find a bunch of other psychedelic/surreal animated bits about counting that I remember from childhood:

• pinball montage
• king of 8
• 12 rocks
• 11 squares
• 10 spies
• Indian yogi counts to 20
• 9-armed martian chick

Also, the famous loaf of bread, container of milk, stick of butter. My memory had been conflating this with another animated short that was much more psychedelic, though, which I can't find. It was a kid traveling through the city alone, encountering various bizarre things on his odyssey. Does that ring any bells for anyone?

Edit: one more: Count To Ten With Nobody.

Edit 2: OK, I could go on forever, but just one more: queen of 6
