Arthur: So? We have ridden since the snows of winter covered this land.
Through the kingdom of Mercia, through...
Guard: Where'd you get the coconuts?
Arthur: (somewhat taken aback) We found them.
Guard: Found them? In Mercia? The coconut's tropical!
Arthur: What do you mean?
Guard: This is a temperate zone!
Arthur: The swallow may fly south with the sun, or the house maarten or the
plummer may seek warmer climes in winter, but these are not strangers
to our land!
Guard: Are you suggesting that coconuts migrate?
Arthur: Not at all! They could be carried.
Guard: (indcredulous) What, a swallow, carrying a coconut?
Arthur: It could grip it by the husk!
Guard: It's not a question of where 'e grips it! It's a simple question of
weight ratios! A five-ounce bird could *not* carry a one-pound
coconut!
Arthur: (exasperated)
Well it doesn't matter! Will you go and tell your master that Arthur
from the court of Camelot is here!

(pause)

Guard: Listen. In order to maintain air-speed velocity, a swallow needs to
beat its wings forty-three times every second, right?

Arthur: Please!
Guard: (patiently) Am I right.
Arthur: I'm not interested!

( A second guard appears on the rampart. )

G2: It could be carried by an African swallow!
G1: Oh, yeah, an African swallow, maybe, but not a European swallow, that's
my point.
G2: Oh, yeah, I agree with that.
Arthur: (extremely exasperated) Will you ask your master if he wants to join
my court at Camelot!!

(pause)

G1: But then of course, African swallows are non-migratory.
G2: Oh yeah...
