There's this other forum I'm a member of, which is themed around randomness. It doesn't have many members or threads, but if you'd like to join I started a general thread about Winnie the Pooh:

But yeah, with Winnie the Pooh being so popular in recent years
AND with an upcoming Pooh movie (why have so many recent Winnie the Pooh movies been released in theaters while the Three Muskateers with Mickey, Donald and Goofy got a direct-to-video release, anyway?) it's a wonder we haven't gotten any boxed sets of this show (or Welcome to Pooh Corner).
One of my favorite episodes is the one where Tigger tries to protect Roo from having to take a bath, and when Tigger switches Roo with Piglet, Kanga actually thinks Piglet is Roo, despite the two looking different. I particularly like Tigger's line "Everybody knows baths are bad for you!"
Another episode I like is, I think titled "Sham Pooh", in which Pooh suddenly loses is appetite, and other characters suddenly become others; honey gets spilled on Owl so Owl becomes pooh, either Eeyore or Gopher becomes Owl, Piglet becomes whoever becomes Owl, and Rabbit becomes Piglet because Tigger (in the role of a detective) suspects Rabbit is Piglet (and Rabbit accepts it when he worries about who'll take care of his garden, much like how Piglet often worries).
And there was an episode where Pooh moved away. I can't remember if Pooh really was moving or if the others mistakenly thought he was moving, but they through Pooh a going-away party, so Pooh moved because of it, and decided to stay with Piglet, keeping Piglet up all night. Eeyore moved into Pooh's home, but moved out when the others threw him a house warming party, mistaking that for a going away party.
Isn't it interesting how in Winnie the Pooh and the Honey Tree, Rabbit seems to live in a small cave of sorts, yet on the series, he lives in a tree (perhaps becase the tree had a bigger front door for Pooh to fit out of?).
