Teddy: Well Charlie, I guess this is it. (sighs) You know, I started making these video diaries to help you survive our...crazy family, and...after four years of doing them, I've realized how lucky we are to be a part of this family. And just know, that...as long as you've got us, you always will have. Come on, guys, say it with me.
Everyone: Good Luck, Charlie!
