[Verginius Rufus]

There are brown birch trees in Indiana, and there are brown birch trees in Korea, and therefore a Chinese eunuch discovered America?

As Fluellen says in Henry the Fifth, Act IV, Scene VII, "There is a river in Macedon; and there is also moreover a river at Monmouth...and there is salmons in both." Therefore Alexander the Great visited England?

[muawiyah]

And you missed the point. These are not just any brown birches, but brown birches that grow straight, and tall, and with a single trunk.

In brief, they are different than other brown birches - a lot different!
