Yeah, David is really flirty with Emily all the time trying to kiss her...haha....poor thing is always embarassed....I'm unable to figure out the equation....he does seem very committed to his wife and kids....so maybe it's just a case of reallllllllllly good friends?? haha....It seems more like he's just really naughty and loves to bug her to get a reaction out of her.....LOLL.....But the chemistry is something else for sure...my fav. bit is that interview where they look at each other and say, 'do we have chemistry'?? LOLL....it's in the way they look at each other....it's natural chemistry....it's just there....can't really be explained....LOLL
