The pickle being eaten by Bulldog (Dan Butler) after he enters Frasier's (Kelsey Grammer) apartment and sits down on his couch gets bigger after Bulldog takes a bite out of it.
When Frasier departs his studio and spots Father Mike in the hallway, a crew member can be seen in Roz's booth moving from where there is not believed to be a door towards the one Roz left through.
