Troi

Troi's job was to emote at the Captain crappily and bone Riker (see below). You give me a more useless character than Troi in this franchise and I'll show you Neelix.
*I think it took her 12 years or something to actually get around to getting it on with poor Riker. God Troi sucks. I'd rather have 2 Jem'Hedar hopped up on amphetamines jumping around my bridge than have this twat telling me about her "feelings".
