My friend has this posted on his profile and I found it most amusing...

Twinkle, twinkle, little star,
We know exactly what you are:
Nuclear furnace in the sky,
You'll burn to ashes, by and by.
But twinkle, twinkle, quasi-star,
Biggest puzzle from afar;
How unlike the other ones,
Brighter than a trillion suns.
Twinkle twinkle, quasi-star,
How we wonder what you are...

Goes to show you astrophysics people (ie. me) are really very nerdy. Heh.
