One sketch that clearly stands out in my mind though I haven't seen it for years, goes something like this. Kermit the Frog is standing on a street corner. In the background, against a brick building, we can see a sign that says, "DONT WALK" in big red letters. He explains that when the sign says, "DONT WALK," it's not okay to cross the street. Then the sign changes to "WALK". He says, "Okay friends, if the sign says WALK, then it's okay for me to cross the street." He starts across the street, only to have the sign quickly change back to DONT WALK. This happens about three or four times, the sign changes, he takes a few steps, the sign changes again and he has to hurry back to reach the safety of the corner. Finally he gets mad and says, "Listen you DONT WALK sign, if you're just gonna mess me up, I'm leaving! I didn't want to talk about DONT WALK in the first place." Then he storms off screen. We hear a loud squeaking noise and the lampost that the sign is on grows two hose looking legs and walks toward the camera! The last time I saw this sketch, I must've been about four years old. Scared me to death!
Then there was another one, though this one had a happier ending, and i was lucky enough to catch this one on video. Maria as Charlie Chaplin comes up to a DONT WALK sign and we hear Gordon's voice off screen saying, "DONT WALK". We wait a few seconds and the sign changes to WALK. Again, we hear Gordon's voice saying, "WALK". Maria starts across the street, swinging her Charlie cane and suddenly the sign changes and we hear all these angry car sounds. She rushes back to the curb and you can tell her heart is racing. This happens about four times, including once when the sign changes and she looks down the street to see if any cars are coming. Then she puts one foot in the street to see if the sign reacts. After the sign changes yet again, she grabs a black screen and puts it over the DONT so now the sign says WALK. You start hearing happy music and she is able to cross the street. Yea! Most of the DONT WALK sketches scared me, even gave me nightmares. I used to dream that the sign would trap me somewhere and if I tried to move, those legs would come out from under the lamp post and eat me! Yeah, I was a strange child...
