Listen to the music. A lot of people ask what that piece is. Well, I'll tell you. It's Papageno's famous aria Der Vogelfänger bin ich ja, from Mozart's Die Zauberflöte (The Magic Flute).
Papageno, as we all know, is a bird catcher.
And that's why it's funny. This commercial doesn't beat you over the head. You either get it - or you don't!
