- Eye Scream: Poppins's eye periodically falls out of its socket and Mac nonchalantly pops it back in with his knuckle, disgusting both Dennis and Charlie.
- Fangirl: Dee is a self-confessed "Grobanite".Dee: I'm a Grobanite. Grobanites don't miss shows. Josh Groban comes to town and we consider it a call to action.

It turns out to be a false alarm, however, as Mac discovers Poppins alive and well, chewing on a diaper at the bottom of the trash can.
