- Each time Thomas is possessed by one of the ghosts. Downey goes full ham impersonating each actor.
- The psychiatric patient who can see the ghosts.
Thomas: Do you really see them? What do they look like?
Patient: There's a gentleman in a brown hat, a nice-looking black lady, a blonde lady with a pink doily, and a young buck in a leather jacket.
Thomas and the Ghosts: [look relieved]
Patient: ...oh, and that naked guy with the nose ring.
Thomas and All Four Ghosts: [glance behind them, confused]
Thomas: No, there's no naked guy—
Patient: You double check me, I double check you.
