Heartwarming: Katy Perry
- Getting the Twitter World to make Rebecca Black's birthday a trending topic after all the slamming the poor girl got because of Friday.
- ET and Teenage Dream for anyone who made it "their song" with their lover.
- Even more so with "Unconditionally" and "This Moment".
- This beautiful duet she performed with autistic girl Jodi DiPiazza for one edition of Night of Too Many Stars. While not seen in this vid, Jon Stewart needed a moment before he could continue being the MC, he was so moved.
