About Trigun .. This might sound stupid, but...

[klinky]

I *believe* this is where it came from:

Vash has a regular(well it's a nice regular) gun.
He has his arm, which turns into a gun.
Plus he has his angel arm.

So you have three different types of guns.

Thus it's "Try-Gun" as in Tri = three.

Klinky nailed it, as did Hakura.

I didn't even see... haruka's statements on the three guns..

my mind blanks past things... most of the time :p
