Actually, the band one is official art I think (I'm an OLD GW fan...crochety almost). Can't verify, but I think it came from an artbook of some sort? Don't quote me on that.

And, third one down, I always get the same reaction.

Heero: Quit it.
Duo: Eh heh heh...
Heero: Quit. It.
Duo: ::snortgiggle::
Heero: Dammit, Duo...
Duo: ::laughs evilly::

Everyone else backs away slooowly...

And in the Type B pic you have to love the smirks. Like "Yeah...we know. We look wicked gay."
