I feel mind control eliminates the purpose of a TG - I mean, what's funny about putting a man in a woman's body if he doesn't even know who he is? And besides, it leaves open the option of lesbianism. That is always fun. There's something about the humiliation factor, as well - if he does not know who he is, how can he fully 'appreciate' his new lot in life. I also like the realism role - it leads to some darker humor as the guy has no friends, no family, no job, etc.
