Fireman vs. Astronaut

I am the fireman throwing some flames.

I am the astronaut flying a saucer.

You don’t say? Well, I will burn you to a crisp.

You don’t say? Well, I will fly straight upwards — the opposite of a nosedive.

You better watch out, O astronaut, for my heat is dangerous.

You cannot defeat me because I can hang from the upper atmosphere.

I wear a flameproof suit.

I wear a space-retardant suit.
