With a market cap north of $340 billion, the company invites incongruous comparisons

There's a new parlor game being played on Tumbler called Things Apple Is Worth More Than.

The rules are simple: Take Apple's (AAPL) market cap -- $346.36 billion as of Tuesday's market close -- and find something huge that has a lower value. There are a dozen entries so far on Tumbler. In chronological order:

• All 32 Eurozone banks
• The Great Wall of China (at $0.52 a brick)
• 45 days of global oil consumption
• The cost of America's obesity epidemic
• Total U.S. corporate income tax for 2011
• The combined value of every home in Detroit and Tampa
• Slightly less than the big three drug makers
• Every home in Atlanta
• 10 times the total paid in federal child support in the U.S. last year
• The five largest ETFs (exchange-traded funds)
• 10 years of silver production
• The combined GDP of Israel, Syria, Jordan and Lebanon

It's a game anyone can play. This particular list is curated by Joshua Brown, a New York City-based financial analyst who writes a blog called The Reformed Broker. You can forward suggestions by e-mail to The Reformed Broker or via Twitter to Downtown Josh Brown @ReformedBroker.
