[net.startrek] Which Regular was also a Guest Star?

Who is the only member of the regular Enterprise crew/cast
to also appear as a guest star in a Star Trek episode?  A
hint:  Don't look for people who were regulars during one
or two seasons and then appeared as guests in another season;
this person was both a regular AND a guest star in the SAME
episode!

William Shatner played a brief cameo shot as the deceased Sam Kirk in 
"Operation Annihilate."  The makeup people put a mustache on him for this role.

I'll take a stab at James Doohan...
I know he can do all kinds of voices and dialects, so he's probably a good
choice.
