And note there is special syntax available when calling a method like 
this: if the last argument is a hash, you don't need to wrap it in 
{braces}

  method1 :email=>"president@whitehouse.gov", :b_day=>"1900/01/01"

If you're writing ruby 1.9 code (and you don't care about 1.8 
compatibility), and all your keys are symbols, there's another syntax:

  method1 email: "president@whitehouse.gov", b_day: "1900/01/01"
