GUARD #1: Where'd you get the coconut?
ARTHUR: We found them.
GUARD #1: Found them? In Mercea? The coconut's tropical!
ARTHUR: What do you mean?
GUARD #1: Well, this is a temperate zone.
ARTHUR: The swallow may fly south with the sun or the house martin
or the plumber may seek warmer climes in winter yet these are not
strangers to our land.
GUARD #1: Are you suggesting coconuts migrate?
ARTHUR: Not at all, they could be carried.
GUARD #1: What -- a swallow carrying a coconut?
ARTHUR: It could grip it by the husk!
GUARD #1: It's not a question of where he grips it! It's a simple
question of weight ratios! A five ounce bird could not carry a 1 pound
ARTHUR: Well, it doesn't matter. Will you go and tell your master
that Arthur from the Court of Camelot is here.
GUARD #1: Listen, in order to maintain air-speed velocity, a swallow
needs to beat its wings 43 times every second, right?
GUARD #1: Am I right?
ARTHUR: I'm not interested!
GUARD #2: It could be carried by an African swallow!
GUARD #1: Oh, yeah, an African swallow maybe, but not a European
swallow, that's my point.
GUARD #2: Oh, yeah, I agree with that…
ARTHUR: Will you ask your master if he wants to join my court
GUARD #1: But then of course African swallows are not migratory.
GUARD #2: Oh, yeah…
GUARD #1: So they couldn't bring a coconut back anyway…
GUARD #2: Wait a minute -- supposing two swallows carried it together?
GUARD #1: No, they'd have to have it on a line.
GUARD #2: Well, simple! They'd just use a standard creeper!
GUARD #1: What, held under the dorsal guiding feathers?
GUARD #2: Well, why not?
