A man is trapped in a room. The room has only two possible exits: two doors. Through the first door there is a room constructed from magnifying glass. The blazing hot sun instantly fries anything or anyone that enters. Through the second door there is a fire-breathing dragon. How does the man escape?

Is this mathematics?

1) Open the sun, open the dragon and hide really well behind the door.  Maybe the dragon will find the sun room before he eats.  With a little luck, the glass is reflective and the friendly dragon will attack itself.

2) It doesn't say the dragon isn't friendly.
