Cory in the House Season 1 Episode 18

I Ain't Got Rhythm

Cory manages to get Vince Valentine, a music executive, to come to the Liberry to watch DC3. Thinking they need to sound as good as they can, Cory decides to hold auditions for a keyboard player. At the end of the auditions, only Stickler is good enough to join the band, which everyone detests at first. After they let him join, he gives them bracelets as a thank you. However, Cory's is a special bracelet that sucks out all of his rhythm! Since Cory can no longer play the drums, Meena and Newt ask him not to go to the performance so they have a chance of getting a record deal. It turns out that this is all a plan by Stickler, for him to become famous instead of Cory!
