Cosmic laws:

1) no matter where you are in the country, you can always find a country / western station on
the radio.
2) No comic book superhero stays dead forever.   Their probability of resurrection is directly
proportional to their perceived capital worth.
3) No science experiment ever goes as planned.  If it appears to have gone as planned, recheck
results.
4) A roadtrip must and always will have an "adventure".  An adventure is any event where the
crap hits the fan and all those involved escape relatively unscathed.
5) Nothing is ever foolproof.  They will always build a better fool.
6) In a classroom setting, there is always going to be: a) that guy who asks too many questions
b) that other guy who is really annoying c) that other other guy who just doesn't get it. 
Sometimes you don't spot 'em right away, but they are always there.  Sometimes, they're really
efficient and it's only one person doing the job of all three...
7) Hindsight is always 20/20
8) Mechanical / electrical / computer problems can never be repeated in the presence of a repair
person.  
9) Despite driving for hours and being on a perfectly straight highway, you will never approach any
hill / peak in Arizona even though you maybe driving straight towards it
