Check out Saint Andrew himself, on The St. Andrews Cross!

There really was a Saint Andrew, and when he was sent to be crucified (before electric chairs and lethal injections were invented) he requested the X-shaped cross. Because he felt he was not worthy to be crucified on a cross-shaped cross like Jesus. I learned this from the nuns when I was in Catholic school. Another explanation is that he was a kinky fucker. If he were alive today perhaps Saint Andrew would be starring in gay bondage porn, like the guys below:

Images above are from Titan, Men On Edge, Bound Gods, Roped Studs and various other sites. The painting is “Crucifixion of St. Andrew,” by the 16th century Spanish painter Juan Correa de Vivar.  Another painting available here.
