Time to cheer up this forum a little.
There was a rumour that when Clinton left the White House his staff removed the ‘W’ key from lots of keyboards as a prank on W Bush.
Here in the UK we had someone at the Treasury leaving a note as a joke when Labour gave way to the Conservative/Lib Dem government. ‘there’s no money left’ is what it said.
Have there been any other famous ones over the years?
And what would you do as a prank if you were Obama or on his staff?
