When one of his supermodel personas is dumped after becoming too old, Roger goes into a deep funk. Hayley tries to cheer him up by introducing him to her yoga class, taught by Gina & Chad. He quickly takes over the class to her surprise by simply being stronger, although Chad notes that they themselves took it over from "pussies."
