I have the distinct memory of making my brother laugh hysterically in the back seat of dad's car during a drive to somewhere or other...probably to Nanny's house. My method? The Manamana song I'd seen and heard on Sesame Street. I may have been about 4 yrs old which would put my stellar performance sometime in 1970? He did the girl's part while I manamana'd my heart out to his pee in his pants, tears in his eyes laughter. My brother is 11 1/2 years older than me by the way. He also liked to tape record me singing my ABC's which I would mess up on purpose like this" A-B-C-D-E-F-cookiemonster....". He also used to get me to attempt to put my foot in my mouth, and being gullible and compliant I tried with a will.
Now we are all growed up and I don't make my brother laugh anymore. At least I'll always have my back seat captive audience memories.
I miss old school Sesame Street with is mild violence (that chef falling downstairs laden with desserts)and weirdness (Fisherman Jones cartoon, Yipyips, psychadelia..). It was so cool.
