What is the worst thing a parent has caught you saying? To the parents, worst thing you caught your kid saying?

I overheard a couple kids talking about how cool it is to have a basement bedroom at their parents house, so that they can swear on Call of Duty all they want. Of course i laughed to myself, the stereotype couldn't have been more obviously hilarious. But it got me wondering, what is the worst thing a parent has caught you saying, whether while playing some sort of online game, or reading of texts, or even on the phone.

Mine personally was my friend's mother reading a text i'd sent, suggesting that the only way i would come over for dinner is if i could eat the chili off of her breasts....and she never brought it up to me.
