Slip of the tongue
 

A guy with a black eye boards his plane bound for Pittsburgh and sits down in his seat. He notices immediately that the guy next to him has a black eye, too.

He says to him, "Hey, this is a coincidence, we both have black eyes; mind if I ask how you got yours?"

The other guy says, "Well, it just happened, it was a tongue twister accident. See, I was at the ticket counter and this gorgeous blonde with the most massive breasts in the world was there. So, instead of saying, 'I'd like two tickets to Pittsburgh,' I accidentally said, 'I'd like two pickets to Tittsburgh'... so she socked me a good one."

The first guy replied, "Wow! This is unbelievable. Mine was a tongue-twister too. I was at the breakfast table and I wanted to say to my wife, 'Please pour me a bowl of Frosties, honey.' But I accidentally said, 'You have ruined my life you evil, self-centered, fat-assed b*tch.'"
