CuriousG is only kidding. Listening to contradictory instructions would not--could not result in an implosion of the entire universe. A simple examination of the forces at work with the application of some elementary logic should make that clear.
Listening to two files which both transform the body, however somewhat opposite of eachother, will not have results, rather, won't do anything whatsoever.
ok, all is answered, but i must toss in my two cents... Blink was unbelievably hilarious in his response to the already-funny CuriousG, and no one seemed to notice... couldn't let it go unnoticed.
I tried the amnesia followed by the memory improvement yesterday, and ended up with a headache today. :P (though I may be coming down with a cold, and it may be completely unrelated to the files)
