Favorite monster moment on Sesame Street? Do you mean like the song "Fuzzy and Blue (and Orange)" featuring Grover, Herry, Cookie Monster and Frazzle? The actual "Frazzle" song? Both of those are good ones. Some of the early 1969 sketches with Bert and Ernie and Beautiful Day Monster are great too. Especially the ones where Ernie gives Bert a "test" and it ends up with Beautiful Day Monster chasing Bert. There's another one when Beautiful Day Monster takes Ernie's cake and leaves Ernie dumbfounded. Lots of good ones.
