Drinking buddies

A couple of drinking buddies who are airplane mechanics are in a hangar at JFK New York. It's fogged in and they have nothing to do.

One of them says to the other, "Man, have you got anything to drink?"

The other one says, "Nah, but I hear you can drink jet fuel, and it will kinda give you a buzz."

So they do drink it, get smashed and have a great time, like only drinking buddies can.

The following morning, one of the men wakes up and he just knows his head will explode if he gets up, but it doesn't. He gets up and feels good. In fact, he feels great! No hangover!

The phone rings. It's his buddy. The buddy says, "Hey, how do you feel?"

"Great", he said! "Just great"! The buddy says, "Yeah, I feel great too, and no hangover. That jet fuel stuff is great. We should do this more often!

"Yeah, we could, but there's just one thing . . . "

"What's that?"

"Did you fart yet?"

"No . . . "

"Well, DON'T, 'cause I'm in Phoenix."

Arthur Holmes

Died 20 Sep 1965 at age 75 (born 14 Jan 1890).English geologist and petrologist was one of the foremost geologists of the twentieth century, who made major contributions to the geochronology of Africa, the genesis of igneous rocks, and physical geology. He developed a method of determining the age of the earth based on measurement of uranium decay in igneous rocks (which invalidated William Thomson Kelvin's hypothesis that the earth's age can be established on the basis of the planet's cooling from a initial molten state). Holmes' method proved to be remarkably accurate and laid the foundation of isotope geology. This was the first quantitative time scale for geology based on measuring the radioactive constituents of rocks.
