The year is 1939, and the USSR is invading Finland.

The Soviet army is marching through the Finnish swamps when they hear shouting from the other side of a nearby hill:

"I bet one Finn can beat ten Soviets!"

The Soviet officer laughs at this and sends ten of his best soldiers to deal with this guy. After a couple of minutes of shooting they hear the voice again:

"I bet one Finn can beat a hundred Soviets!"

The officer, now enraged, sends a hundred soldiers to silence this cocky Finn. A few minutes of shooting and screaming later, the voice shouts again:

"I bet one Finn can beat a thousand Soviets!"

The officer is now absolutely furious with this enemy, but knows that nobody could possibly beat 1000 soldiers alone, so he accepts the challenge once more and sends 1000 of his men. Nearly 15 minutes of shooting, screaming, and bright flashes later, a lone Soviet soldier comes crawling back over the hill with severe burns, covered in blood and half of his leg mangled. Panicked, he yells to his comrades:

"Don't go up there! It's a trap! There are actually two of them!"
