Replying to 2 tickets to pittsburgh

Two guys are drinking at a bar.

The first says "Do you ever start thinking about something, and when you go to talk, you say something you don't mean?".

The Second guy says "Yeah, I was at the airport buying plane tickets, and the chick behind the counter had these huge tits, and instead of asking her for 'two tickets to Pittsburgh' I asked for 'two tickets to Titsburgh'.

The First guy says, "Yeah, well I was having breakfast with my wife last week, and instead of saying 'Honey can you please pass me the sugar?', I said 'You stupid BITCH, you're ruining my life'.

sorry if a repost, but this joke always gets me.
