A) He is protesting recent DNA testing being
performed on mummified cavemen.
B) Being a devout creationist, he thinks the

believing this to be the logical way to debunk all the caveman nonsense.
C) Rusty spends way too much time on IRC (where his
nick is 'CaveDave'), and has lost all touch with reality.
