a manicurist (
the engineer's burly assistant (9)

They all tumble out when Mrs. Claypool (Margaret Dumont) opens the door.

Here are a couple of lines:
Henderson: What's a hermit doing with four beds?
Otis B. Driftwood: Well, you see those first three beds?
Henderson: Yes.
Otis B. Driftwood: Last night, I counted five thousand sheep in those three beds, so I had to have another bed to sleep in.
You wouldn't want me to sleep with the sheep, would you?
*****
Otis B. Driftwood: That woman? Do you know why I sat with her? Because she reminded me of you.
Mrs. Claypool: Really?
Otis B. Driftwood: Of course, that's why I'm sitting here with you. Because you remind me of you. Your eyes, your throat, your lips! Everything about you reminds me of you. Except you. How do you account for that? (aside) If she figures that one out, she's good.
