The Book of Pooh - Episode 21 "The Words Are Out / Brain Drain"

Aired May 24, 2001. Piglet wakes up one morning with laryngitis and Pooh believes that his "words are lost," so he promises Piglet he'll find those missing words. / Eeyore forgets something he was trying to remember, and Owl comments that he's having a "brain drain." That simple comment puts everybody in fear that they're all suffering from the "brain drain" and in danger of forgetting everything.
