Several groups of men would get together every month or so to socialize and debate whatever topic was presented for discussion. At one such meeting the debate raged over why the head of a man's penis was larger than the shaft. After a very spirited discussion and without reaching a consensus it was decided three different groups would research the matter and report their results at the next meeting.
At the next meeting once the discussion was opened for debate the three groups were called up to present their findings. The first was an average size group with adequate funding. They stated they'd spent two weeks and about a thousand dollars and concluded the head was larger than the shaft to give the man more pleasure during sex. The second group immediately disputed this and presented their own findings. This was a larger well-funded group. They stated they'd spent almost a month and about ten thousand dollars and concluded the head was larger than the shaft to give the woman more pleasure during sex.
This didn't seem to resolve the issue so the third group presented their findings after which it was decided by all any further discussion was pointless. This was a small group with very limited funding. They stated they'd spent a week and about ten dollars and concluded the head was larger than the shaft to prevent a man from hitting himself in the forehead.
