That reminds me of an old joke:
A freshman college student from Texas is walking around the campus at Harvard on his first day. He meets a senior. He finds out that they are both business majors, both interested in investing, and both own IDMI !
So the Texan asks: "What price did you get IDMI at ?"
The senior replies: "I'll tell you in a second, but first I would like to say that here at Harvard, we don't end our sentences with a preposition."
The Texan responds: "Oh, well, sorry. So, what price did you get IDMI at asswipe ?"
