How many __________ does it take to change a lightbulb?

In case you were wondering how many polish people it takes to change a lightbulb, the correct factual answer is 3. I have the following story to prove it.
A friend of mine went on March of the Living a few years ago as an advisor/counselor/whatever they call it. He said one night in Poland, as he was walking around the "hotel", making sure all the kids were in their rooms, he noticed one room where the light was flashing on and off. He stopped in the room and asked the kids what was going on in there. He saw them flipping the lightswitch up and down, up and down, on and off, on and off. He asked them what the hello they are doing. They told him they were trying to burn out the lightbulb so that they could then call the desk and get someone to come change it and they they could finally know the answer to "How many polish people does it take to change a lightbulb?". Being a responsible advisor, he could not let this go on. But being curious and having a sense of humor, he did, and he stayed to find out the answer. Eventually, they wore out the lightbulb and they called down to the front desk and asked them to send someone up to change the lightbulb. A few minutes later, into their room walked 3 men with a ladder. So there you have it. How many polish people does it take to change a lightbulb? The correct factual proven answer is 3.
