"Cessna Cleared for Take-Off" joke

(Supposedly a true story - then again, aren't they all?)
This Certified Flight Instructor and his Student are holding on the runway for
departing cross traffic when suddenly a deer runs out of the nearby woods, stops
in the middle of the runway, and just stands there looking at them.
Tower: "Cessna XXX cleared for take-off."
Std: "What should I do? What should I do?"
Inst: "What do you think you should do?"
(Think-think-think.)
Std: "Maybe if I taxi toward him it'll scare him away."
Inst: "That's a good idea."
(Taxis toward deer, but deer is macho, and holds position.)
Tower: "Cessna XXX cleared for take-off, runway NN."
Std: "What should I do? What should I do?"
Inst: "What do you think you should do?"
(Think-think-think.)
Std: "Maybe I should tell the tower."
Inst: "That's a good idea."
Std: "Cessna XXX, uh, there's a deer down here on the runway."
(Long pause.)
Tower: "Roger XXX, hold your position. Deer on runway NN cleared for immediate
departure."
(Two seconds, and then - I presume by coincidence - the deer bolts from the
runway, and runs back into the woods.)
Tower: "Cessna XXX cleared for departure, runway NN. Caution wake turbulence,
departing deer."
It had to be tough keeping that Cessna rolling straight for take-off.
