In another thread, I said it was a shame that Herbert Birdsfoot was excluded from the Sesame Street Unpaved book, yet it's even more of a shame that Prof. Hasting was included, but with a picture of Dr. Nobel Price! I'll never understand how they made such a mistake. Prof. Hastings and Dr. Nobel Price are from different eras, look nothing alike, have completely different personalities, and really had different occupations, one being a teacher and the other a scientist. I love the Sesame Street Unpaved book, but those kind of things seemed so careless.
Anyway, I really liked Prof. Hastings and I wish they would have tried to develop his personality more before giving him the axe.
Although he was only from 1970, I believe they did show reruns of his skits until around 1973.
