[The Unspeakable One rises in front of Rimmer]
Rimmer: Boy, am I glad to see you. You must be the Unspeakable One. Just to fill you in, there's been a gigantic administrative cock-up. Some of your staff have somehow mistaken me for a virgin.
Unspeakable One: Stop your putrid whining, you dank gift of rectal public hair.
Rimmer: Sorry. Yes, I do tend to jabber on when I'm a bit nervous.

Rimmer: Look, I'm trying to keep my temper, but you really are pushing your luck now miladdikins.
Answer: The cello is a large four-stringed instrument, which, when it is played, stands vertically on the floor between the player's legs (assuming they are seated). If it is to grow as large as the other instuments mentioned will, it would require a rather unseemly lack of femininity to be able to encompass it with the legs.
