Whoa. Thats kinda crazy. But at the same time reminds me of a stupid romantic comedy movie I saw a while back on Comedy Central. I forget the name of it but it was about a dude that didnt know his parents and had a thing for Susan Summers growing up.
Anyway he fell in love with this chick who he later found out was his supposed sister [insert wacky hijinks here], but later found out it wasnt true at all [insert more wacky situations leading up to this revalation] but at the end after they got married come to find out that his real mom WAS Susan Summers and she came to the wedding and it freaked him out because well *cough* And it ended on that note.
Thats kinda like that but not really. Wow what a messed up movie that was. Anyway no real point just wanted to relate that movie to that topic. If it were me well hmm I dunno I know Id feel awkward shaking her hand. Id ask if she could hook me an autograph picture for the family album or some free videos..that would give a new definition of Home movies
