Favorite uncle? It's a debate

My favorite uncle, James (pictured above), is coming to town for Labor Day. Is it really my favorite uncle? Well, the debate is still out because I don't remember these alleged comments. You must know the story first.

When I was 8 or 9, we lived in Pittsburgh. My uncle Bob and his wife (at the time) came & stayed with us for a week. A few days after they left, the phone wrang & I answered. The caller said "It's your favorite uncle!!" and I allegedly said "Uncle Bob!!" and the caller said "No, your other favorite uncle".

Again, I don't remember saying these things so the jury is still out.
