A Polish, English, and French guy are running away
from the German soldiers when they come up to a forest and they decide
to hide by each climbing a tree.
When the Germans arrive, they go to the first tree
where the English guy is, and shout, "We know you're up there; come
down." The English guy, thinking fast, says, "Tweet, tweet,
tweet..."
The Germans, thinking that it's a bird, move on to
the next tree where the French guy is and once again shout, "We know
you're up there; come down."
The French guy, thinking fast, says, "Hoot, Hoot,
Hoot..." The Germans, thinking that it's an owl, move on to the
next tree where the Polish guy is and once again shout, "We know
you're up there; come down."
The Polish guy thinks for a while and then says,
"Moo, moo, moo..."
