Almost everything Quack says or does.

-->'''A random Rabbit:''' That's not corn! That's a guy!
** The birds finding out about their shadows and being convinced that they're real. The episode has a number of funny moments, but one that stands out would be Chirp trying to ''feed'' her shadow because it "looks a little flat". Even the narrator thought it was funny!
-->'''Chirp''': (''drops some seeds onto her shadow'') You simply must try these seeds from the forest. They are quite delicious!
-->(''[[{{Beat}} beat]]'')
-->'''Chirp''': (''angry'') ''[[SuddenlyShouting EAT SOMETHING!!!]]''
** The episode with the fog. Quite possibly the only episode to employ huge amounts of slapstick, almost always from Quack.
** Chirp talking in her sleep:
-->'''Chirp:''' (''asleep'') You're right Quack...ducks ''do'' know best...I wish I were a du--(''wakes up'') AHHH!\\
'''Peep:''' (''wakes up with a start'') What is it?\\
'''Chirp:''' Sorry Peep...I had a nightmare!
