Hooked on a Ceiling - Yakko, Wakko, and Dot help Michelangelo paint the ceiling of the Sistine Chapel

Goodfeathers: The Beginning - Squit must find some food if he wants to become a Goodfeather. The initiation test proves to be more difficult than it seems at first.

This episode was okay but not really my thing. I should probably just stick to the episodes that have Pinky and the Brain in them.

H.M.S. Yakko - Yakko, Wakko, and Dot travel to an island where they encounter a pirate and sing songs composed by Gilbert & Sullivan for the Pirates of Penzance but with new lyrics.

Fun, decent, but not great.

Animaniacs 1.02

Yakko's World - Yakko sings a song which identifies all the countries of the world

Cookies for Einstein - Yakko, Wacko, and Dot attempt to sell Kid Scout Cookies to Albert Einstein

Win Big - Pinky and the Brain - Brain competes on Gyp-Parody, a game show, hoping to win enough money to buy the device he needs to take over the world

Thoughts

Yakko's World might have been accurate when this cartoon first aired but that is no longer the case.

The Warner siblings sing the opening song to Pinky and the Brain. They also make a cameo appearance later in the segment. 

This episode opens with the story behind the Warner siblings, although it is a slightly shorter version than opened the previous episode.

The episode closes with the Warner siblings spinning the wheel of Morality.
