Which astrological sign is most prone to cheating?

Ashley Madison, a dating website explicitly for those who are already in a relationship (their tagline is "Life is Short. Have an Affair") have analyzed the astrological signs of their members to determine which star sign is most likely to cheat. Here's what they found:

  • Among men, Pisces are the most likely to cheat, while, among women, Geminis are the least faithful.
  • Aquarius and Cancer are the next most likely men to cheat; Aries and Virgo women come in second and third.  
  • However, female Geminis also get their comeuppance: They're the most likely to be cheated on. Among men, Tauruses are most likely to have spouses who cheat. 
  • When it comes to duration of affairs, Aries men and Virgo women are the most prone to maintaining a long-term extramarrital relationship.

What do you think? Is there any stock in star signs?
