Worlds funniest joke?

“So, Marvin walks into the bar.
He says "I have this great joke."
The bartender says "What'll it be?"
Marvin says "How many tight yellow T shirts do you have?"
Bartender "No jokes buddy! out of here before I call out my rabbit, er, uh, rabbi, er uh, rabid blonde to do what has never been done before for only 25 cents"
Bartender: " Do you want a drink or not, buddy?"

Marvin: "water, no ice"”

“A hooker, an engineer, and a politician were discussing what actually was the world's oldest profession. The engineer said to the hooker "Despite the old story about prostitution, engineering is the world's oldest profession." The politician asked "I disagree, I maintain politics is the world's oldest profession. Why do you claim engineering?" The engineer replied, "Before anything else happened there was creation. Creating the universe from nothing was the greatest possible engineering feat." So the politician asked "What existed before Creation?" "Chaos" was the engineers reply.

"Aha!" smiled the politician.”

“Three doctors were discussing various patients and surgery in the lounge. The first doctor said librarians were the easiest surgical patients. All the parts are in alphabetical order. The second said, "No, electricians are the easiest. All the parts are color coded".

The third said "Congressmen are the easiest." How can congressmen be easy?, was the quick reply.

"Because," said the third doctor "They have no brains, no guts, no heart, no backbone, and their head and their ass are interchangeable."”

“A lady from California purchased a piece of timberland in Oregon. There was a large tree on one of the highest points in the tract. She wanted to get a good view of her land so she started to climb the big tree. As she neared the top, she encountered a spotted owl that attacked her! In her haste to escape, the lady slid down the tree to the ground and got many splinters in her crotch. In considerable pain, she hurried to the nearest doctor. He listened to her story then told her to go into
the examining room and he would see if he could help her. She sat and waited for three hours before the doctor reappeared. The angry lady demanded, "What took you so long?!" The unperturbed doctor replied, "Well, I had to get permits from the Environmental Protection Agency, the Forest Service, and the Bureau of Land Management before I could remove old-growth timber from a recreational area."”
