Hmm - it turns out that in Farscape, it's "Crichton".

I liked the ep where some mysterious weapon switched their minds around -
Rigel's mind moved into Crichton, Crichton's mind goes into Aeryn, the
totally hot babe, and her mind moves into Rigel.
A few minutes later, Crichton realizes he's in Aeryn's body, so he stands
there and masturbates (as a hot babe, of course). After all, what
self-respecting geek _wouldn't_ masturbate if he suddenly found himself
occupying a female body? <leer, snort>
Cheers!
