Swallow carrying a coconut

"Are you suggesting coconuts migrate?" "Not at all, they could be carried." "What -- a sallow carrying a coconut?" "It could grip it by the husk!" "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 coconut." "Well, it doesn't matter. Will you go and tell your master that Arthur from the Court of Camelot is here." "Listen, in order to maintain air-speed velocity, a swallow needs to beat its wings 43 times every second, am I right?"
