First off, awesome episode.
My favorite part was the real clips of a rubber chicken and baby alligator. Kinda dissapointed Pinkie's hair didn't go flat. Oh well.
Couldn't help but notice this, but during the Pinkie's song, when she's looking at her family photograph of the party, there's actually four fillies. Her, Inkie, Blinkie, and a filly in the front. Maybe a another sister or cousin?
