A man dies and goes to hell.
As he approaches the gates he is stopped by the gatekeeper who asks for his name.
"Joe." he replies.
"Well, joe, I've found your name on the list. There are seven levels in hell, but since your only sin was cheating on a science test in the third grade, you will only be in the first level."
"Oh, it won't be that bad then.", joe replies.
"Joe, that's the hottest level because heat rises. You'd know that if you studied for your test."
A blond went to a flight school insisting she wanted to learn to fly.
As all the planes were currently in use, the owner agreed to instruct her by radio on how to pilot the solo helicopter.
He took her out, showed her how to start it and gave her the basics, and sent her on her way. After she climbed 1000 feet, she radioed in. "I'm doing great! I love it! The view is so beautiful, and I'm starting to get the hang of this."
After 2000 feet, she radioed again, saying how easy it was to fly. The instructor watched her climb over 3000 feet, and was beginning to worry that she hadn't radioed in.
A few minutes later, he watched in horror as she crashed about half a mile away.
He ran over and pulled her from the wreckage. When he asked what happened, she said, "I don't know! Everything was going fine, but as I got higher, I was starting to get cold. I can barely remember anything after I turned off the big fan!"
According to the second law of thermodynamics, you're supposed to share your body heat with me.
Two Eskimos and a Kayak
Two Eskimos sitting, paddling along in a kayak, when one felt a little chilly so he made a little pile of sticks and lit a fire in the craft.
His friend shouted at him to put it out, but the warning was ignored.
Unsurprisingly, the kayak sank quite quickly and finding themselves in the cold water, the second Eskimo whacked his idiot mate over the head with a now redundant paddle.
"Ouch!!" said the previously warm Eskimo, "what did you do that for?!?"
"Because, you idiot," said the second Eskimo, "Don't you know that you can't have your kayak and heat it too??"
