Just in case you don't know, the boards here have scripts for most (all?) of the episodes. You can find the link on the middle top of the main board page, or just go here: http://www.lcficmbs.com/scripts/

The script for the first part of the pilot includes the following:
Quote
PERRY
Well, tell him to keep his pants
on. And where's my lunch? If
Carlini's can't deliver on time,
find a place that can.
(a sigh, to Clark)
I bought a blood pressure monitor
last week, you believe it? Hell,
I'm only fifty-two.

CLARK
Paava leaves.

PERRY
Excuse me?

CLARK
The Yolngu tribe in New Guinea eat
paava leaves to relieve stress....
puts them in a meditative state.
Maybe you should try it.

PERRY
Uh huh. Sounds like you've done
some travelling.

CLARK
(nodding)
I spent some time in a Llamasary in
Tibet and with the Sherpas in
Nepal. I just got back from
Australia. I've been studying the
Dreamtime theory in Aboriginal
mythology.
So you're right that the scriptwriters included it. As for why they'd make that mistake, I think the point about internet searches being very different in the early 90's is an excellent one. Hard to believe Google hasn't been around forever, isn't it? LOL.
