Nickelodeon: Shrek 2 Adverts (2004)
Okay, so most of these aren't actually produced by Nickelodeon, but they all ran on Nick during the week leading up to the movie's release. There's a pretty neat commercial in here for Baskin Robbins, and for the record--no. I don't have the first 5 minutes of the movie. Don't ask me for it.
