Tribune Co.’s new owner, billionaire and orator nonpareil Sam Zell, let Chicago Tribune intern Katie Hamilton know exactly what he thought about her recent prank on rival paper the Chicago Sun-Times — one that has produced its fair share of chatter in the Windy City.

Hamilton and her colleagues submitted a music video that they sent to the Sun-Times, which offered a cash prize to whomever could produce the best video protesting Zell’s plan to sell the naming rights to the city’s historic Wrigley Field.

Here’s the memo that Zell sent to Tribune employees and that we got hold of:

Partners,

I returned from out of the country this weekend to learn that one of our employees had entered a video in the Sun-Times contest designed to protest a name change of Wrigley Field.

Needless to say, I was shocked! Appalled! The video was a blatant disregard for Tribune Company policy. It demonstrated a glaring disrespect for your chairman and CEO. (I’m much better looking, clearly more agile, and I think whoever played me was singing off key.)

So, I immediately referred to the 11th commandment: Thou shalt not take oneself too seriously. And, then I shared the video with my family and friends.

It’s most definitely worth the watch, and it was a deft grab of the ball away from that other paper. What was their name again?

Maybe he’s laughing to keep from crying.
