Everyone knows George Clooney can be a practical joker...but teasing the "Most trusted person in America" seems a little mean spirited.

The late Walter Cronkite was invited over for a dinner with Clooney and about 15 friends, Clooney telling the former TV Anchor that they dressed the event. When Cronkite came out dressed nicely, decked in a blue sport coat and captains hat, he was shocked to see everyone else sitting in their robes. He after muttering something, went to change. While he was changing the rest of the dinner party put on suits.

But when Cronkite returned in shorts and saw everyone else dressed to the nines, he simply walked past all of them and jumped in the lake.
