Blondes are not stupid

A Russian, an American, and a Blonde were talking one day.

The Russian said, "We were the first in space!"

The American said, "So, we were the first on the Moon!"

The Blonde said, "So what! We're going to be first on the
Sun!"

The Russian and American looked at each other and shook
their heads.

"You can't land on the Sun, you idiot! You'll burn up!"
said the Russian.

The blonde replied, "We're not stupid! you know.
We're going at night!"
