Unfortunately, yes.
I LOVE this special, but it has a somewhat black cloud over it for me. I first saw it in probably late 1989, just after moving to Florida. It was still back in the day when it was the routine of my sister and I to watch Sesame Street, Mr. Rogers, and Captain Kangaroo together (me being almost two, and her being five or six). After seeing this special, I refused to watch SS most of the time. Why? Very simple.
THAT FLAMINGO SCARED ME HALF TO DEATH! He still does! I really have a hard time watching scenes with him, even now, and as a result, I went through early childhood without watching but the two or three episodes of Sesame Street we had on tape. That's likely why I started watching it again when I was 8...to make up for lost time.
Otherwise, it's a wonderful special, I can't reccomend it enough (this being the second of the two Phil Donahue episodes, a crack up as always when he seems to take offense when he's told he doesn't need a microphone to talk in person).
