This is hilarious.
Total eclipses are rare because they require the tilted orbits of the sun, moon and earth to line up exactly so that the moon obscures the sun completely. The next total eclipse will occur in 2008.
For future reference, things that happen every 18 months should not be considered rare.
Not So Fast 
I have to remember to stay away from the kitchen and all the knives during the next eclipse. That’s good advice. 🙂
