There were three astronauts, a Russian, an American, and a Not-So-Bright American.

The Russian says we were the first in space. The American says we were the first on the Moon. The Not-So-Bright American says I will be the first to land on the sun.

The other two look at her and say, "The sun! Wont you burn up?"

She says, "Well duh! We are going to land on it at night."
