Personally, I see no motivation for Cheri to lie about Mike's placing, as TA asserted. Why would she care what anyone thought, if indeed Mike did come in last? It's just a message board, and anyone who would lie to strangers about something so easily checkible... well... I'm sure they have bigger things to worry about in life than what strangers on message boards think of them.
Besides, with as many times as Cheri has called other people liars, I couldn't imagine her putting herself in such a position by lying about this. I don't care what the pics say- I'm SURE she didn't lie.
