Gregory and Carl knew that the Joans' were going on an airplane, so they went with them. When they got off the plane they were surprised to see that they were in the Amazon.
As soon as they stepped off the plain they saw someone who looked exactly like Carl! Gregory and Carl asked, " Who are you?"
" I am Karl, Carl's evil twin! Muahahaha!" Karl said.
"I have a twin?! I didn't even know you even existed!"
"Yes, you do have a twin, and I have existed just as long as you have, but I was born first!"
Gregory butted in, "So what makes you so evil?"
Karl replied, "I CHEAT IN THUMB WRESTLING!"
"I bet I can beat you!" said Carl, then he whispered to Gregory, "Remember when I lifted that penny?" Gregory nodded.
"Bring it!" Karl said.
They chanted, " 1, 2, 3, 4, I declare a THUMBWAR!"
After awhile of intense thumbwrestling, Carl declared, " I WIN!"
And with that Karl ran away in devistation. They never saw him again.
