Derpy Hooves, the fan-favorite pegasus with crazy eyes, can be seen throughout the episode: several appearances in the public during Rainbow Dash's dream between 03:35 and 04:11, during Rarity's dream around the 8:11 mark and briefly at 17:13 and 18:13 during the chase for Twilight Sparkle.
Friendship Report: Twilight learned that sharing one's blessing can affect friendship when there isn't enough to go around.
This episode was actually the first written and produced, back when the show was originally going to have two 11-minute stories per episode. Specifically Applejack and Rarity's voices sound slightly different, with Applejack's slightly higher-pitched, Spike doesn't show his crush on Rarity, and teleportation appears harmful.
The title of the episode is a parody on the website, Ticketmaster.
