How’d you get the black eye?

Two men are sitting next to each other on a train, both sporting black eyes. Naturally curious, the first man looks at the other and says, “So, how’d you get the black eye?”
The other man replies, “Well, it was a Freudian slip.”
“What’s that?” the first asks.
“It’s when you mean to say one thing, but you accidentally say another that reveals what you’re really thinking,” explains the second.
The first man nods. “Oh. So what happened?”
“Well,” says the second, “I was buying my ticket for the train, and the woman at the counter had the biggest boobs I’d ever seen. So when I meant to say ‘two tickets to Pittsburgh,’ I accidentally said ‘two pickets to Tittsburgh’—hence the black eye.”
The first guy laughs and says, “That’s funny, something similar happened to me. This morning, I was eating breakfast with my wife, and I meant to say ‘could you pass the jam,’ but I accidentally said, ‘you ruined my life, you stupid bitch!’”
