When the Denver Broncos played the Baltimore Ravens in the divisional round of the NFL playoffs, the mayors of each city made a good natured bet. The forfeit for Denver's mayor Michael Hancock was to reenact the dance Baltimore Ravens linebacker Ray Lewis does before each game. After putting off an initial attempt due to an alledged "injury", Hancock finally paid up
Can't really imagine the Lord Mayor of Dublin doing anything like this. In fairness to Hancock he can move pretty smoothly and does Ray Lewis justice.
