I viewed a similar thread on a socionics forum, and I thought it would be fun to try out. So here we go.
How many _ _ _ _ s does it take to screw in a light bulb?
ESTJ: 34. One to sign the registration papers for unscrewing the old light-bulb, five more to have permission papers signed by the authorities to set up a ladder and unscrew the old light-bulb, two more to send in official forms to the City Bureau of Light-Bulb Replacements for official access permission to access the new light-bulb, three at the City Bureau to redirect it to the proper sub-Bureau, three more at the sub-Bureau to have the official forms queried, subjected to state inquiry, and otherwise scrutinized. The rest pass it from cubicle to cubicle, through a ridiculous and near-infinite chain of ludicrous bureaucracy.
ESFP: One, two, three, maybe even four, five or more. Who knows? All they seem to care about is partying.
ESTP: One. He rudely tells the light-bulb to screw itself.*
ISFP: Light-bulbs waste energy. ISFPs prefer to use more eco-friendly light-sources, such as candles
ISTP: This is pretty self-explanatory. After all, ISTPs are "The Mechanics."
ENFJ: ENFJ dramatically says, "O Romeo, wherefore art thou?" The disgruntled ISTP then replies, "Shut up and answer the question."
ENTJ: Two. One to yell "What?!? What manner of light-bulb would dare to make such a mockery of me?!? It shall rue the day it was ever created!" The other to angrily screw in a new light-bulb and proceed to ruthlessly destroy the old light-bulb.
INTJ: Three. One to screw in the light bulb and a second to methodically analyze the source of the original error, create an algorithm for future improvement, and to analyze the velocity, angle, etc. of the first INTJ screwing the light-bulb just for fun. The third INTJ will use the willpower of the ENTJ and the ingenuity of the ENTP to create a global monopoly on light-bulbs. In reality though, this is all just an attempt to distract the general public from his master-plan for world domination.
ENFP: (See answers for both ENTP and ESFP)
ENTP: None...light-bulbs are the way of the past. Behold! My new ingenious creation! Never again will anyone every have to change a single light-bulb for the rest of one's life!
INFP: Two. One to screw it in, and another to write a 230-page melancholy poem about how the old light-bulb is symbolic for the human race.
INTP: Meh, only one, but he will be too lazy to actually do it. He'll probably just use the constant glow from his computer as his main light-source. All of this, of course, assumes that he actually notices that the old light-bulb will have gone out in the first place, since he is more involved in reading books on advanced algebraic topology and quantum chromodynamics, not to mention daydreaming, toying around with a Rubik's cube, hacking, and illegally downloading Star Trek episodes.
I'm a horrible joke-teller, so please do attempt some of these on your own.
