A scientist finds evidence of an actual dinosaur, alive and living in the rainforests of South America.  He campaigns several universities and succeeds in getting a grant to launch an expedition.

Several weeks pass and the expedition party stumble upon a 3 foot tall pigmy standing near a 300 foot long dead dinosaur.

The scientist approaches the pigmy and exclaims, "Wow!  Did you kill this dinosaur?"

"Yep!" replied the pigmy.

"But, it's so big and you're so small!"

"Yep!", replied the pigmy.

"How on earth did you kill it?" inquired the scientist.

"With a club," replied the pigmy.

"How big is your club?" demanded the scientist.

The pigmy replied, "Well, there're about 50 of us!"
