Pranking has a long tradition in politics...
Bush Sr. pranked the Clinton administration when they took over the White House... and of course Clinton staffers famously stole the "W's" off of all the White House keyboards when they left...
So lets set the scene... You're President Bush... you're leaving soon so now is the time to plan your prank for the new President and his staff....
What do you do to the McCain staff?
What do you do to the Obama staff?
*try to keep it good natured folks... who knows... we may come up with some fun stuff to do to our own office mates.
For me...
Obama: I get GIANT ears for Obama and all his staff... he's got some wicked skin flaps on the side of his head.

McCain: I sign up for the AARP discount card and have it sent to his staff.
