V Word
Episode 1917
Oscar gets a letter from a viewer who wants Oscar to talk about a V word. Oscar talks about the V word "Vibrate". Telly doesn't know what "vibrate" means, so Oscar has Telly hit a steel V that Oscar has with a hammer, which gives them both a vibrating feeling.
Quiet and Loud
Episode 1928

Episode 2043

The Letter X
Episode 2049

Telly reads a letter from Robin Sunshine of Happyville, Montana. Oscar is repulsed by this information, but intrigued by their question - "Why are you such a crabby old Grouch?" Oscar fumbles coming up with an answer, but then produces a triangle and a square. He gives his answer - "Why is a triangle a triangle? Because it's a triangle. Why is a square a square? Because it's a square. And I'm a grouch because I'm a grouch." Telly doesn't accept this and points out the geometric reasoning behind the names.

Silly Answers
Episode 2465

Telly reads one anyhow from Mrs. Grimble Grouch of Kitty Litter, North Carolina - "What makes you think anyone should listen to your silly answers anyway?" Oscar is insulted by such a silly question and refuses to give her the satisfaction of an answer. Telly doesn't find the question silly and asks why Oscar even runs this show if he feels he shouldn't be listened to in the first place.
