A guy with a very black eye boards his plane bound for Pittsburgh and sits down in his seat. He notices immediately the guy sitting 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?"

Other guy: "Well, it just happened. It was a tongue twister accident. See, I was at the ticket counter and this gorgeous blonde with huge breasts was there, so instead of saying 'I'd like a ticket to Pittsburgh', I said 'I'd like a picket to Tittsburgh', and she hauled off and hit me in the eye."

First guy: "Wow, this IS a coincidence. Mine was a tongue twister too. I was at the breakfast table this morning, and I meant to say to my wife, 'Please pass the box of Wheaties', but I accidentally said 'You've ruined my whole life you stupid bitch.'"
