Nick Searcy and Norman Lloyd don't appear in this episode - Searcy probably because he was setting up for his double-role in the next episode as well as working on the story on it. (edit)

Frank: Making babies the old-fashioned way. You just can't beat it. Am I right? (edit) Frank: (distracting bad guys) Oh my God! Bigfoot! (edit) Olga: (The baby's) making noises again – I think there's something wrong. (edit) Olga: I had no intention of the gun going off. Its trigger was a hare.
Frank: Its trigger was a rabbit? I think the expression is 'hair-trigger', Olga.
Olga: Shut up! (edit) Frank: Scavenger hunt in a middle of a Russian winter – sounds like a good time waiting to happen.
Olga: Don't remind me – I had 20 of those winters and I still haven't thawed out.
Frank: Tell me about it. (edit)

At about the middle of the episode, when Parker takes the baby, if you look carefully you can see an editing cut. (edit)
