I remember the episodes with Telly's broken arm:
How it happened was that he was playing Triangle Tag with Elmo and he tripped over a bike which belonged to some girl named either Ruthie or Lucy...forgot which.
Also remember the times Telly and Luis went to the hospital for a check-up by Dr. Sing (yes, as his last name suggests) Telly went to get his (and Freddy's) X-ray, at one point he thinks that he can't use his other arm to write, but Luis encourages him, kids came to sign Telly's cast...and he realizes that there's a whole line of people wanting to sign his cast! At the end of that episode Elmo signed Telly's cast and they played together (outer space?)
In another episode, Telly was at the Arbor Area singing "Broken Arm Blues" (with a Honker in the little circle playing the bugle) Later on, Oscar comes out of his can and tells us that he actually feels sorry for Telly's arm, so he'll hide in his can and not come out. Telly comes by and he's like "Hey Oscar. What are you doing? I know you were there, I just saw you..." He bangs on the can: "Come on, Oscar, What are you dooiiinngg???" He opens the can lid and Oscar's eyes peek out and Oscar replies "I'm hiding from you! That's what!" And he says why. Telly thinks "that's so nice of you" Oscar says it's not and that leads into an arguement, which he seems to be enjoying.
One episode Telly stood outside Oscar's can and several kids came to sign his cast, including a cow. Oscar came out and he wanted to sign it too, but Telly refuses (forgot why Telly refused, but I was thinking because he'd pull a prank or it's because he's a grouch). Oscar's second attempt was in front of 123, where he convinces Telly to let him by telling a story about a Grouch and little blue monster (the Grouch in this one was the one used for Gary Grouch) and my memory seems to be little hazed up and I can't exactly make out what the puropse of it was, but it ended with the monster falling into a puddle of mud. At the end, several adults are with Telly at the counter outside the Fix-It-Shop and Oscar comes in, and finally convinces him. Telly eventually gives in, and Oscar signs his cast with his name. Telly then gave Oscar a big hug (much against his will).
Later on, Telly finally got his cast removed, and his arm recovered). At the near end of the episode, he and several others (including Maria) were near the trashcan, where Telly shows off what he can do with his arms (making a butterfly) And, he knocks on the can and gives Oscar the cast pieces, which he admires and says "Thanks"(!)
