Erica and parrot

Erica is walking out of a movie theatre at the same time as a man with a parrot on his shoulder.

Erica turns to the man and says, "Your parrot actually seemed to understand the movie".

It looked around during the boring parts, it paid close attention to the dramatic parts, it even "squawked" during the funny parts.

I don't understand how that can be.

The man turns to Erica and says "I don't understand it either.... he didn't like the book at all".
