An actual conversation at work over the cube walls:

Coworker 1:  Hey Nick.  What comes after a trillion?
Me:  Why are you asking me?
Coworker 1:  Because you seem to know everything.
Me:  Oh jeez.  I think it's quadrillion.
Coworker 1:  I think you're right!
Coworker 2:  Don't encourage him.

That of course lead into the a conversation regarding the names of the other really really big numbers, and the number of atoms in the universe.  Yeah... we're all geeks.
