text: Mayor Bloomberg ... the Broadway star? It must just be the Inner Circle charity dinner, an annual roast of City Hall journalists and politicians! Bloomberg's rebuttal performance, held this year at the New York Hilton Hotel on March 23, 2013, featured the mayor being joined on stage by the casts of four Broadway shows, including "Rock of Ages," Nice Work If You Can Get It" and "Annie." Here, Bloomberg gets a lift from the ladies of "Nice Work If You Can Get It" while performing in his last Inner Circle Dinner. Check out more photos of the mayor hamming it up ...
  
  The mayor gets cheeky! Performing with the cast of "Rock of Ages," Mayor Bloomberg unleashed his inner rock star, strumming a guitar while donning a leather jacket. When the "Rock of Ages" cast jokingly told the mayor he's been elected as the new pope, he quipped, "Ive been a chief executive so long, I dont know if I could be a number two."
  
  Could a spot on "Dancing With the Stars" be up next for Mayor Bloomberg after his time in office? The mayor certainly had his hands full, dancing with the cast of "Nice Work If You Can Get It." In another skit with the "Annie" cast, the mayor and his fellow actors poked fun at Hurricane Sandy. Every time Annie's dog Sandy was mentioned, Bloomberg, along with the rest of the actors, reacted in horror.
  
  Mayor Bloomberg also had a little fun at New Jersey Governor Chris Christie's expense. Speaking about Sandy, Bloomberg said, for me, when I hear that name I expect Chris Christie to hug me.
  
  Who knew the mayor was such a showman? Bloomberg danced on stage at the 91st annual show, which was entitled "Last Gulp."
  
  This wasn't the first time Mayor Bloomberg, who was joined here by the cast of "Rock of Ages," made a splash at the Inner Circle Dinner. Check out some of the memorable costumes New York City mayors have donned throughout the years at the annual Inner Circle charity dinner ...
  
  Mayor Bloomberg ditches his suit and tie for... a Spider-Man getup? The mayor went for laughs at the 2011 annual dinner.
  
  Bloomberg also took on the role of a character from Broadway show 'Mamma Mia!' with cast members Judy McLane, Lisa Brescia and Jennifer Perry at the Inner Circle dinner.
  
  In 2010, Bloomberg traded in his mayoral power for flower power, joining the cast of 'Hair' in a spoof called 'Mair.'
  
  Rocking shoulder length chestnut locks and a hippie-inspired head band, Bloomberg appears to be in something of a haze.
  
  Where can we find a shirt like that?
  
  In 2009, the mayor took a rather bizarre take on 'The Little Mermaid' in a skit that began with Bloomberg crashing his plane into the East River after learning he can't run for a third term as mayor.
  
  We're not sure what's going on here during this 2008 skit, but we're loving the mayor's red bow tie.
  
  Mayor Bloomberg takes the stage next to Mary Poppins in a 2007 skit. They say a spoonful of sugar helps the medicine go down, but he doesn't look too thrilled by what's being ladled up.
  
  Having a billion dollars can apparently buy you a flying umbrella. Beats having to take the subway to work.
  
  We gotta respect a guy who's willing to dance on stage wearing suspenders and a straw hat. Here Bloomberg shows us his moves during a rendition of Mary Poppins.
  
  Is that King Arthur or Michael Bloomberg?
  
  This may be New York City, but Bloomberg joined the cast of 'Chicago' to bring a few laughs to dinner guests in 2004.
  
  Here, he shows us his jazz hands.
  
  Mayor Mike Bloomberg performs with the cast of 'Chicago.'
  
  Looking mighty in his suit of armor, Bloomberg expressed his dream to 'rule the unrulable city' in his 'Mayor of La Mancha' skit in 2003.
  
  Still dressed in armor, Bloomberg mounts a burro as he exits the stage. Oh, the jokes...
  
  Mayor Rudy Giuliani, sans pants, kicked it with the Rockettes during a 2001 skit.
  
  Rudy Giuliani, or Don Giuliani? The former mayor channeled his inner mobster during a spoof of 'The Godfather' in 2001, but it's kind of hard to take him seriously in those heels.
  
  He can dance, too! Giuliani broke out his white disco suit and hit the stage in 2000.
  
  What a beast. Mayor Giuliani put on fur and horns for his 1998 parody of 'Beauty and the Beast.'
  
  But not for long! Giuliani shed his beastly fur and emerged a prince. We wonder where's his Beauty?
  
  Giuliani got himself all dolled up for the 1997 Inner Circle dinner, but the show turned out to be kind of a drag.
  
  The mayor appeared alongside Julie Andrews, dressed as a man, in his spoof of Broadway show, 'Victor Victoria.'
  
  Call him Grease Lightening. Rocking leathers and a motorcycle, Giuliani appeared with the cast of 'Grease' during the 1996 dinner.
  
  Clearly, he's excited about his role.
  
  Mayor Ed Koch gets a hand up during a 1986 Inner Circle dinner. We're loving the whole stripes on plaid look.
  
  Eaten alive! Koch gets swallowed up by a plant from 'Little Shop of Horrors' during a 1985 spoof.
summary: Take a look back at some of the more memorable costumes New York City mayors have donned throughout the years at the annual Inner Circle charity dinner.
