A post-doc, a grad student, and their professor are taking a walk outdoors during lunch when they come upon an old brass lamp. They pick it up and dust it off. Poof! Out pops a genie! "Thank you for releasing me from my lamp-prison," he says, "I can grant you three wishes- one for each of you."
The post-doc thinks a moment, and then she says, "I'd like to be out sailing a yacht across the Pacific, racing before the wind, with a crew of totally buffed-out, gorgeous guys." "It is done," says the Genie, and Poof! the post-doc disappears.
The grad student thinks a moment and says, "I'd like to be riding my Harley with a gang of beautiful women throughout the American Southwest." "It is done," says the Genie, and Poof! the grad student disappears.
The professor looks at where the other two had been standing and rubs his chin in thought. Then, he tells the Genie, "I'd like those two back in lab after lunch."
