How many jonnyrau's does it take to change a lightbulb? Four or more. One to remove the bulb. Another to ebay it and for its residual value. Another to perform an arbitrage deal on a new bulb bought at ASDA but returned to Sainsburys for profit of 5p. And one to hold the ladder (on which further deals could be done, necessitating more Jonnyraus...).
