I don't have a high-quality copy of this, except with better audio.
From Season 3 (1971). At the carnival, Herry asks Ernie to participate in a game. Ernie has three chances to win a prize by knocking down a pile of bottles with a baseball. Ernie only manages to knock down some, then most of the bottles, but not all of them, so he doesn't win the prize. Herry, on the other hand, can knock the bottles down not with a baseball, but with his loud voice.
