There's no reason Trip couldn't have spent the whole series in the blue underwear.
Yes there is. I have no desire to be struck blind by the sight of THAT.
Now, if we're talking T'Pol and Hoshi, then I'd say that they'd be overdressed in the blue underwear.
Why would you be struck blind? Do you really find Trip in his blue underwear unappealing? I understand if you don't find anything there to be attracted to but repulsed??
There are girls in this too, but you might have to cover your eyes during the Trip parts.
