Happy Birthday to:

R&B singer Usher (1978)

Stealing a plot that must feel awfully familiar to guest star Jennifer Aniston, 30 Rock takes a turn for the dangerously psychotic (instead of the usual simple, funny psychotic antics of Tracy and Jenna) in its third episode for the season of the same number with a stalker storyline.

Happy Birthday to leggy blond beauty Stacy Keibler (1979), R&B singer Usher (1978), British musician Thomas Dolby (1958), actor/magician Harry Anderson (1948), Moody Blues singer Justin Hayward (1946),
