Five Sesame Street Stories1985

Big Bird:
Is Oscar still playing his violin, Grover?

Super Grover:
No. He has stopped.

Big Bird:
Then why are you still making that horrible face?

Super Grover:
My super-hearing tells me that Oscar has stopped practicing his violin. But my keenly developed sense of super-smell tells me that Oscar has just... cooked his dinner! It smells like old socks with sardine sauce. Yecch!
