The sole purpose of studying these persons is to actually find the ankles in question.
Many different instruments are used in this study. These include Microscopes, Telescopes, Kaleidoscopes, Stethescopes, Gyroscopes, Horoscopes and the Hubble.
In past years magnifying glasses were in use by Reubanktologists across the globe. However, sufferers of Reubankle have arranged a petition, signed by many followers, to ban the use of these useful instruments in the study of Reubanktology.
The reason for this sudden desire to lead a magnifying glass-free life appears to be due to the want of Reubanktologists to use the magnifying glass as a method of magnifying the suns rays many-fold and applying singe marks on the feet, heels and shins of Reubankle sufferers.
The Reubanktologist Guild repudiated this petition, saying that the magnifying glass was the most simple way of finding the elusive ankles of Reubankle sufferers. It seems they magnify the suns rays to a pin point, and then slowly move the pin point of heat/light across the area where the Reubankle sufferer's ankle should be. When they hear a yelp they know they have located the ankle.
Apparently the ankle's of Reubankle sufferers have only been located four and a quarter times in the history of mankind, making Reubanktology an extremely unrewarding profession.
"Yes, I know that man. He studies Reubanktology."
"Oh really? No wonder he looks so grumpy!"
