[javascript] How to access the first property of a Javascript object?

Is there an elegant way to access the first property of an object...

1. where you don't know the name of your properties
2. without using a loop like for .. in or jQuery's $.each

For example, I need to access foo1 object without knowing the name of foo1:

var example = {
    foo1: { /* stuff1 */},
    foo2: { /* stuff2 */},
    foo3: { /* stuff3 */}
};
