My show idea

Get me and a male host.  Every week we get a new challenge of some sort that's beyond our regular abilities, i.e.

• juggling flaming clubs
  
• racing cars on a track
  
• learning to use a trapeze
  
• surviving Hell Week at the Citadel
  
• working a weekend as a line cook
  
• learning a "Dancing with the Stars" style routine
• doing the Men's Health Urbanathlon

For things that are just a sporting event with a clear winner, that host wins.  If it's something based on style points the audience can call in afterwards to vote.  Which ever host wins gets a chunk of money put in the bucket for the money they'll donate to a charity at the end of the season.  Also, the audience can also add money to whichever host's bucket they choose.

At the end of the season, both charities will receive money from the hosts, but the winner of the season is the host who gave more money.  I think some nice physical challenge based battle of the sexes could make for good ratings.

TV producers - give me a call!
