That reminds me...Atop the supermutant radio place in NV (with the whacked out DJ) the mexican mechanic dude was a ghoul you could also have as a follower.
In NV also, the chick in vegas you recruited at the old Mormon Fort as a hooker for the bar was a ghoul also.
That was an odd fetish: A sadistic cowgirl GHOUL?
Of course, NOTHING beats F.I.S.T.O.
"I can't feel my legs!!!"
Oh yeah, he was my favorite follower both story wise and perk wise (your equipment degraded extremely slowly with him as your follower).
I think I remember the hooker, I did that quest chain and you had to bring them a hooker from the bar. I remember thinking who would pay for THAT? lol.
