Simply look at a bright light from the corner of your eye. I don't know why, but it works.

This works because

the nerve involved in causing your sneeze sits right next the the nerve that gets all excited when you look at a bright light. There is some kind of cross over of leccy and volia a sneeze.*

Overstimulation of the Optic Nerve (by bright sunlight) can cause the
Trigeminal Nerve to misfire. This is a genetic 'defect' which occurs in about 35% of the population. Interestingly, it's a genetically dominant trait so, if you ever have kiddies they should inherit it from you.
