Episode 0294


 * While everyone is picking up the litter on the street, Bob tells Big Bird that if somebody could figure out a way to stop people from littering, he would be a real hero. Big Bird records his voice, shouting "Don't Litter! Don't Litter!" He's told that it's too noisy, and it'll probably stop people from sleeping. In a final effort to be a hero, Big Bird hangs "Don't Litter" signs all over the street -- on the buildings, on the doors, on the windows, etc.


 * Oscar demonstrates his secret knock that you must learn in order to be a member of his secret Grouch Club.


 * Ernie brings an umbrella, a flashlight, and a bowling ball to the bathtub, just in case the electricity goes out, the roof leaks, and somebody shows up asking to borrow a bowling ball. Just like he predicts, all of those things happen.


 * Michael Landon and the cast of Bonanza count to twenty. (Also in Episode 0131)


 * Bob blows up a balloon (bigger) until it breaks (smaller).


 * Three Muppets have fun scatting to hand-clapping.


 * Big Bird makes a Big Bird clock (which is similar to a cuckoo-clock). He sets the hands of his clock to 9:00, and runs in and out of doors nine times, tweeting each time.


 * Ernie and Bert have pizza and grape juice. Bert complains that Ernie has more of each, so Ernie tries to make it even by eating some of his pizza and drinking some of his grape juice, but then Bert has more.


 * Cookie Monster and Herry sing "Circles". (Also in Episode 0131)


 * Oscar insists that he plays with a baby rattle like a rattlesnake.


 * Tom (in English) and Maria (in Spanish) review two groups of glasses as they sing the Sorting Song.


 * Maria points out that C is for camera; a kid points out that C is for carrot; Tom points out that C is for candle.


 * Tom suggests that Oscar and some kids try to do different things with their mouths: open as wide as possible, open and close as fast as possible, make funny faces with their mouths, and pucker up and make kissing sounds.
