Excerpts from: http://www.gatago.com/alt/atheism/22540864.html

The main problem with "Bless you" is that if you sneeze again, you feel
really guilty. They either have to re-bless you or aknowledge that the
original blessing didn't work. The best you can tell them is to not
worry about it, it wasn't an attack from Satan, it was just a sneeze.

I use gesundheit, which is German for health. Either that or "Get away
from me, you filthy, lurgy infected swine. Who do you thik you are,
Typhoid friggin' Mary?" It always goes down well at parties. ;-)

"Bless" means to bleed. "God bless you" therefore
translates to "god bleed on you." The phrase isn't offensive,
it's bizarre.

I always say "you are so good looking!"
Besides, who the hell is arrogant enough to think they have the power to bless me?

I like to say damn you.. but people frown upon that.

Actually, eons ago, it was believed that when a person sneezed, that they could actually pass their spirit through their nose. So it became a way to bless the soul of the person who sneezed. ancient greece or egyptian roots

Gesundheit meant "health", but not for the one who sneezed, rather the one sneezed on. Try that one. People will still think you're trying to be polite.
