Two-Brains getting attacked from behind in one of the shorts by Huggyface and he is left on the ground with his butt in the air and his eyes at different directions.

The Butcher's word mispronunciations are always amusing, but the best ones have to be when he actually says a different word instead, completely changing the meaning of his statement. The best example would have to be in "Granny May's Book Club". After Granny catches Word Girl and brings her and Huggy to the Villain Association to prove she doesn't have to retire, he proclaims "Now she doesn't have to respire!" Word Girl's deadpan correction and definition of "respire" just makes it even better.
In "The Rise of Miss Power", just when we think Mr. Botsford Took a Level in Badass and is about to save the day... we find that he's still Too Dumb to Live and he just did something totally useless.

Wordgirl: Uh, see you caught me by surprise there...
From "House Arrest": Chuck having a conversation with Becky and WordGirl "at the same time."
From "Monkey Business": Becky "almost" realizes she forgot Huggy at the last battle many times, but the last one where she realizes she forgot to get the mail! Did you "see" how much she swung her arms walking to the door?
