There aren't many laughs to be found in the series, though the BBC radio drama adaptation is slightly more campy and includes a few more funny lines — quite a few of them courtesy of Pantalaimon, who's become a bit of a Deadpan Snarker in this version.
On getting Iofur Raknisson to cooperate:
Pan: Flatter him. Tell him he smells nice.
On locating the window through the worlds:
Lyra: It's really like a window? Will: Yeah — only — it's not like anything you've ever seen before as well. Pan: That's helpful. "Like a window you've never seen before." Huh!
In the museum:
Lyra: A human skull with holes in it? And there's Stanislaus Grumman's! Pan: You've got a thing about skulls. Lyra: I haven't! Pan: Have. Lyra: The museum's deserted. Let's ask the alethiometer about it. Pan: It'll say you have an unhealthy obsession, and you ought to take up playing the recorder.
