The Running Gag of Gopher falling down his self-dug holes.
Pooh sneezing and causing Rabbit's decorations to fly onto him.
And before that, Rabbit trying to make Pooh's bottom like a moose trophy, but Pooh giggles as Rabbit draws the mouth, making it all crooked.
Rabbit: Oh Pooh, you messed up my moose!
(cut to Pooh on the other side wearing a similar expression as the "moose")
When Rabbit overhears Gopher offering honey to Pooh, he yells, "Honey?! OH NO!" He then begins to run outside, only to trip over a chair with a rather priceless expression.
And shortly after stopping Pooh from eating honey and telling him that he'll taste it for him, Rabbit leaves and then comes back to hammer a sign that says, "Don't Feed The Bear" with his own fist, saying, "DON'T! FEED! THE! BEAR!"
At the beginning of the scene, Pooh is sleeping like a baby, while on the other side, Rabbit is sitting there completely stressed with eyes wide open.
"Christopher Robin, I have come to a very important decision. These are the wrong sorts of bees!"
Winnie the Pooh and the Blustery Day
Pooh and Piglet are blown onto Owl's window.
Owl: Well, I say now. Someone has pasted Piglet on my window.
