In this YouTube clip, "Jessica," an adorable kid, wakes up full of beans and spends 49 glorious seconds enumerating all the awesomeness in her life before the bathroom mirror. If this doesn't make you happy, you are dead inside (especially as she opens her rant with "Look, I can be a SHARK!").
Update: And here's the same delightful kid, grown up to the age of 13, being awesome (Tx, Pesco!)
