A guy is flying in a hot air balloon and he's lost. So he lowers himself over a field and shouts to a guy on the ground:
"Can you tell me where I am, and which way I'm headed?" "Sure! You're at 43 degrees, 12 minutes, 21.2 seconds north; 123 degrees, 8 minutes, 12.8 seconds west. You're at 212 meters above sea level. Right now, you're hovering, but on your way in here you were at a speed of 1.83 meters per second at 1.929 radians"
"Thanks! By the way, are you a statistician?" "I am! But how did you know?"
"Everything you've told me is completely accurate; you gave me more detail than I needed, and you told me in such a way that it's no use to me at all!"
"Dang! By the way, are you a principal investigator?"
"Geeze! How'd you know that????"
"You don't know where you are, you don't know where you're going. You got where you are by blowing hot air, you start asking questions after you get into trouble, and you're in exactly the same spot you were a few minutes ago, but now, somehow, it's my fault!
Two statisticians were traveling in an airplane from LA to New York. About an hour into the flight, the pilot announced that they had lost an engine, but don’t worry, there are three left. However, instead of 5 hours it would take 7 hours to get to New York.
A little later, he announced that a second engine failed, and they still had two left, but it would take 10 hours to get to New York.
Somewhat later, the pilot again came on the intercom and announced that a third engine had died. Never fear, he announced, because the plane could fly on a single engine. However, it would now take 18 hours to get to New York.
At this point, one statistician turned to the other and said, “Gee, I hope we don’t lose that last engine, or we’ll be up here forever!”
A statistic professor plans to travel to a conference by plane. When he passes the security check, they discover a bomb in his carry-on-baggage. Of course, he is hauled off immediately for interrogation.
"I don't understand it!" the interrogating officer exclaims. "You're an accomplished professional, a caring family man, a pillar of your parish - and now you want to destroy that all by blowing up an airplane!"
"Sorry", the professor interrupts him. "I had never intended to blow up the plane."
"So, for what reason else did you try to bring a bomb on board?!"
"Let me explain. Statistics shows that the probability of a bomb being on an airplane is 1/1000. That's quite high if you think about it - so high that I wouldn't have any peace of mind on a flight."
"And what does this have to do with you bringing a bomb on board of a plane?"
"You see, since the probability of one bomb being on my plane is 1/1000, the chance that there are two bombs is 1/1000000. If I already bring one, the chance of another bomb being around is actually 1/1000000, and I am much safer..."
A man and a woman asked, what is the probability that he/she went out into the street, meet a dinosaur.
Man begins to count and, finally, gives his version: "Taking into account all the possible factors - zero point three trillion.
She also meets once: "Fifty-fifty. "Why?" - Say it. "It's very simple: either meeting or not meeting."
A statistician confidently tried to cross a river that was 1 meter deep on average. He drowned!
I thought I'd start the ball rolling with my favourite.
"Being a statistician means never having to say you are certain."
A mathematician, a physicist and a statistician went hunting for deer. When they chanced upon one buck lounging about, the mathematician fired first, missing the buck's nose by a few inches. The physicist then tried his hand, and missed the tail by a wee bit. The statistician started jumping up and down saying "We got him! We got him!"
