I just mean that it's got a lot of humor -- good humor, too -- in a show where you wouldn't expect that type of thing. A lot of it has to do with delivery and timing. Here's one of my favorite examples:
OWL: This clearly is written in a forgotten language of the Ancients, likely thousands of years old! Judging by the script, something from the Lower Lumbar Region.
POOH: But Owl, I think it was sent from Christopher Robin because he's in trouble.
OWL: In that case, this is most definitely a recipe for coconut cream pie.
TIGGER: It's a disaster! An apostrophe! There's no tellin' what kind of terribibble trouble the poor guy's in! Why, he could be in the clutches of kid-eatin' canibibbles!
RABBIT: There are no... canibibbles in the Hundred Acre Wood.
TIGGER: Then probably it's... kid-eatin' sharks! Yeah! Tigger sharks -- the stripety kind... Wait a second. There are no sharks in the Hundred Acre Wood. Wrong time of year.
