They have protomass bubbles that are 'exhalified' by they woobidy-vortex protoenergy wigwamp-wavelengths- unless 'degenerate' people are around, in which case the bubbles vorically de-spin in the counter-magneto mojo field and concretize and embedded psycho-squiggles (these look like mountain dew, BTW). The Aliens take these Degenerated anti-plasminic psycho squiggles and distill the exuded tzo-crystal extract they get from placing it in the F- W.I.T. (Fantastic Wonderful Integrational Timemachine) device- that was designed from reverse engineering the Old Testament and doing an selective word replacement from the Bhagavad Gita and last weeks copy of the 'Dilbert' comic strip.

Anyway, Back to the Tzo Crystal Extract. The aliens ferment the Tzo Juice that dribbles out of the F.W.I.T machine and then use it to power the vortical phase-cancellation drive, which they use to zip around abducting people and probe them in uncomfortable ways.

Why are you looking at me like that? oh, you are one of those ignorant and stupid 'science' people who believe in the false Profits of Logic, Reason and Empirical validation of Hypothesies! Oh, well, you are just beyond hope. You lack the faith necessary to see the real truth behind the universe! Modern Medicine, A life span of 80+ years, freedom from crippling pain, and an infant mortality rate of 1/5th of what it was before science? Well, We could have found that by properly decoding the Bible.

Anyway. I have some more Tzo Juice to voricalize to [insert science-like-cool-made-up-word] and [insert perposterous claim] and decode the mysteries of the universe. Bet YOU wish you had MY intellect
