@cherrie,
There is no way of knowing whether or not 'Bertie the baseball bat' in the second part of the sentence is the same thing as 'Bertie the baseball bat' in the third part of the sentence. For example: Imagine there is a cube and a sphere. Both the cube, and the sphere, are called 'Freddi'. In that scenario if i write "Freddi fell off of a table today.", then there is no way of knowing whether i am referring to the cube or the sphere (end of example). Just because Rudolfo calls his bat 'Bertie the baseball bat' doesn't mean that there isn't another thing, that is not Rudolfo's bat, that is also called 'Bertie the baseball bat'. Now, it does say that Rudolfo was unable to find his own bat, and said it in a manner which implies that everything after that would have to be related to Rudolfo's bat in some way. This is true, however, we can another argument. What if finding 'Bertie the baseball bat' in the third part of the sentence is just a step to finding 'Bertie the baseball bat' in the second part of the sentence (we already established that 'Bertie the baseball bat' could be referring to two different things, the bat, and an unknown object). For example: You want to complete Objective A. In order to complete Objective A, you must first complete Objective B. The problem arises when Objective A and Objective B are both normally referred to as just The Objective. If you say "I am going to complete The Objective.", then the question becomes, were you referring to Objective A, or Objective B? (end of example) The same argument can be applied here. In order to find 'Bertie the baseball bat' that is mentioned in the second part of the sentence, I must first find 'Bertie the baseball bat' that is mentioned in the third part of the sentence. Now when you say "I am going to find 'Bertie the baseball bat'.", the question becomes, were you referring to 'Bertie the baseball bat' in the second part of the sentence, or were you referring to 'Bertie the baseball bat' in the third part of the sentence? Both are equally valid. Both are equally valid because every assumption made about the situation Rudolfo and James are in is plausible. This is because we do not know the full situation that James and Rudolfo are in. It is because of this that Rudolfo could be referring to two different things that are both called 'Bertie the baseball bat'. This allows for two different interpretations of the statement, and therefore, the statement does not work.
