Elmo: It's very nice to meet you, Tricky! It's like "Trick" with the "Y" at the end! (Laugh track.) Tricky the Clown(bored): Hmm. Jack Black: Y'see, Tricky your name is a synonym for "Difficult". Tricky the Clown(confusedly): Wait, isn't this lesson about shapes? Jack Black: Tricky, what is a square normally called? Tricky the Clown: A quad-thingy what kind of question is that? Elmo: You know, on the playground my friends and I loved to play on the slide. (Pause.) Tricky the Clown: Okay, I'll wait. Oh, you're finished? I was under the impression that this show's called "Sesame Street" not "Red Puppet Thing and Fat Man never shut up". Tricky the Clown: Ask me 'bout the sides and the vertices of the shapes. Elmo: My favorite game is called "Buck, Buck!". Tricky the Clown(annoyed): Enough with your blabber! Tricky the Clown(sadistically): How 'bout I kill the both of you with my stop- Jack Black(taking the stop sign): Ooh! Cuckoo-Coo-Coo! A stop sign! Perfect! Tricky the Clown(angrily): HEY! GIVE IT BACK! Jack Black(goofing off): Ooh! I think I'm gonna go skiing down there! I'm going down! Cuckoo-coo! (Audience and main cast of Sesame Street are laughing.) Tricky the Clown(angrily): NO! DON'T LISTEN TO HIM! THAT'S NOT FUNNY! WHAT YOU'RE SEEING IS WHAT HAPPENS WHEN Y'GO SKIING! (Tricky tries to reach his stop sign but, he falls down.) Tricky the Clown: AH! Jack Black(goofing off): Oh, I'm going down the slope and going Zip! Zap! Zippy do! (Audience and main cast of Sesame Street laughing.) Tricky the Clown(angrily): NO! STOP APPLAUDING THEM! THIS MAN'S NOT USING REAL WORDS ANYMORE! Jack Black(as Tricky is climbing on him to retrieve his stop sign): A little girl is playing jump rope with her big sister! Elmo: Coo-Ca-Choo! (Laugh track.) (Jack pulls Tricky off his shoulder and holds him in his hands.) Elmo(eerily): C'Mon, little clown you love jump rope, don't you? Tricky the Clown(frightened): I...love jump rope. Jack Black(eerily): You're gonna sit here and enjoy it? Tricky the Clown(frightened): I'm gonna sit here and enjoy it. I love cookies and E.T. is the best movie I've seen since, Evil Dead. (Tricky sits on Jack Black's lap and sucks his thumb while, he and Elmo are watching him.)
