Yeah. I was fighting a Slowpoke when this happened. I didn't want to send out my Geodude, Wooper or Slugma, so I kept on switching between my Totodile and Togepi, because it would keep using yawn. It finally stopped using yawn after I switched back to Togepi, so I decided to use Metronome because I thought something useful would happen. But, nope, I was wrong.
