Two years ago Dave took on my wager that Big Macs would rise in price faster than oil. One fifth of the way into the ten-year term, things are going in his favor:

	Oil	Big Mac	Ratio
1 Dec 2005	$58.75	$3.06	19.2
27 Jan 2006	$67.35	$3.15	21.4
6 Apr 2007	$64.28	$3.10	20.7
1 Dec 2007	$89.00	$3.41	26.1

The current Big Mac price comes from the Economist's Big Mac Index of July 2007. The price of light sweet crude is from 321energy.com.

Here's a chart showing the petroleum surge.
