1x39 - Kick Buttowski: Suburban Daredevil

Kick's principal threatens to expel him if he pulls one more stunt inside the school. Unfortunately the school janitor decides to frame Kick for a crime that wasn't his to begin with, and now Kick must clear his name before it's too late. It is revealed in this episode that Kendall and Ronaldo are in a secret (and as shown in this episode and later episodes, possibly strained) relationship with each other.
