Double trouble.

Simon:  I can't believe they thought this piece of cardboard could stop us.  Are you thinking what I'm thinking?
River:  Well, I'm pretty sure I can fit under there, but you may end up stuck like Winnie the Pooh.

The picture of contentment.

River looks a bit jealous that two bunnies can't fit in the oat container tunnel at the same time.  Simon looks pretty content with this situation.
This pic makes me laugh every time I see it.  For some reason, it reminds me of Winnie the Pooh stuck in Rabbit's House.

Ah, it still has that new oat smell!
