I don't hate Perez as a viewer because I don't mind when he winds up up housemates I don't like. Thing is though he winds up nearly all the housemates even the ones I do like! I imagine he would be a nightmare to actually live with.
I must admit I did giggle when Alex blew him kisses. Perez was asking for that really. Harassed the man repeatedly by all his fake coughing then following him around the house blowing kisses.
(I don't condone the word Alex called him though)
So it was pretty funny watching Alex revel in giving him a taste of his own medicine with the blowing kisses thing. And him saying "aww are you ok brother?" with false concern.
