Not knowing anything about what ie.contains_text does, it's hard for me 
to say why it might return 62 instead of TRUE. What is TRUE, anyway? Is 
it the same as "true", that is, the global value that is the single 
instance of TrueClass?

In Ruby, everything except false and nil are true. That is, all numbers 
including 0 are true, as are all strings including "". The global value 
"false" is the single instance of FalseClass, and the global value "nil" 
is the single instance of NilClass.
