For a adament atheist/NON-christian historical geology prof start

fundamentalist christian background because we all know the the Earth is
really only 6000 yrs old so this really didn't happen, but I'll answer it
anyways..."

the room, bring your own.

  Pretend to discover gold on a sample in the room that has pyrite on
it.  Run out of the room screaming loudly that you've found gold and how

adjective) test.  Then come back into the room and say, "HA! I fooled ALL
of you!"

  Yell loudly, "Oppressed geology undergrads of the world -
CRYSTALIZE!"



  Bring a Brunton Compass and inform everyone around you that this
ISN'T the orientation the room was in the last time you were there.  Then
tell them that it is a vicious plot of the geology department to use
techtonic forces to move all to rooms on campus so that everyone will
sucumb to their devious plans to rule the Earth...etc...etc... 



  Bring a stuffed animal that looks really bizarre.  Mid-way through
the exam, walk up to the front like you're in show-n-tell and tell the
class in a cute 5 year old voice about your buddy, "Isogyer."



  Bring a soft black rock (carbonates, coal, ...etc...etc...)
and write the entire exam with it.

envronmentalist wackos. 



  Use a petrographic microscope to look at the exam.

  Come to the exam late and before you sit down at a desk strike it
with a pick.  Carefully listen to the tone and pretend it isn't right.

times each.  After you finally find a place to sit, get up every fifteen
minutes and do it all over again and find another place to sit. 



  When you get the exam, give it back to the professor and tell him to

  Pull out a decent sized chunk of gypsum and begin to gnaw on it. 
Explain that it makes for a great aphrodisiac.

COMMING BACK AND THEY'RE PISSED!"
