An engineer, a physicist, and a mathematician are shown a pasture with a herd of sheep, and told to put them inside the smallest possible amount of fence. The engineer is first. He herds the sheep into a circle and then puts the fence around them, declaring, "A circle will use the least fence for a given area, so this is the best solution."
The physicist is next. She creates a circular fence of infinite radius around the sheep, and then draws the fence tight around the herd, declaring, "This will give the smallest circular fence around the herd."
The mathematician is last. After giving the problem a little thought, he puts a small fence around himself and then declares, "I define myself to be on the outside!"
Another one along similar lines as this one:
An engineer, a physicist, and a mathematician are all in town for a conference, and they all happen to be staying at the same hotel. In the middle of the night, the engineer wakes up and smells smoke. Sure enough, he looks in the hall, sees the fire. He looks for a second longer, sees a fire hose, and immediately drenches the fire and goes back to bed.
Later on, the physicist wakes up smelling smoke. He gets up, looks in the hall and the same fire must have restared, because it's in a blaze. He looks closely and sees the fire hose, sits down to calculate how to put out the fire with a minimum amount of water, and puts out the fire as efficiently as possible.
The same night, the mathematician wakes up smelling smoke and goes out into the hall. He sees the fire blazing again, and looks around a little more. He then sees the fire hose and immediately declares "Ah! A solution does exist!" and goes back to bed.
A little less clean:
One day bob looks over at his neighbor washing his car, and notices that it's all dented up and there is grass, mud, and blood all over the place. "Hey dan, what'd you do to your car?" he asks. "Ahh... it was terrible, I hit a lawyer on the way home from work today. " he replies.
"Well, that explains the blood and dents, but how'd you get all that grass and mud all over the place?" Bob inquires. "I had to chase him through the park first."
And even less clean:
One day two long lost friends run into eachother and decide to have lunch the next week. Upon showing up for the appointment, each observes that the other's left eye is all bruised and swollen. "Wow, what a coincidence. How'd you get your black eye Dan?"
"Aww, it was this weird tounge twister thing. I was at the ticket teller the other day and what I meant to ask for was a 'Ticket to Pittsburgh' but the teller was the gorgeous blond with an amazing rack, and what I accidentally said was 'could I get a picket to tittsburgh' and she straight out decked me."
"How ironic!" declares Bob, "mine was all due to a tounge twister too! The other day I was having breakfast with my wife and what I meant to say was 'Honey could you please pass me the wheaties' but what I accidentally said was 'You fvcking b1tch you're wrecking my life..."
