game of thrones - In which episode did Joffrey force a man to put his arm on a hot pot?

Which episode of "Game of Thrones" includes a scene where Joffrey forces a man to put his arm on a hot pot?

I know it's stupid, but I'm almost sure that such scene was in there. However I can't find any reference to it.

Could anyone help me (beside a shrink ;) )? I mean point out the right episode, or deny its existence?
