Stop Me if You've Heard This Before

A German, an Englishman, and a Canadian,
Brought together by their love of model airplanes,
Those working ones that can fly by remote control,
And by simultaneous August vacations,

Talk shop convivially under the whining
Of their little wonders looping over the lake,
Until one puts his plane into too steep a dive,
The German, and it stalls and crashes in the waves.

A fool on a boogie board, surfing the creek mouth,
Paddles out obligingly to rescue the toy.
Someone makes a joke about the German losing
The dogfight, and only the Canadian laughs, 

Enough to sound polite, then goes to the German
As to a dumb brother, to give him good advice.
