We're 100% confident in calling these people THE most effed up parents of 2012. And not just because it's December and we've seen all the other effed up parents. Even if these two had landed on our radar back in January, no one could touch them.

Two parents in Plymouth, Pennsylvania decided to teach their son about sex by having him have sex with his mother while his father gave pointers.

If that isn't horrible enough on the surface, they had him have sex with his mother for the first time on his eight birthday. And that was one year after his father started him showing him porno.

At his parents' trial last week, the boy, who's now 14, testified that he was so sheltered being homeschooled that he didn't even realize what he was doing was wrong until years later.

His 45-year-old mother was convicted of conspiracy to commit rape of a child, corruption of minors, endangering the welfare of a child, and incest.  His 53-year-old father was convicted of the same charges, plus distributing explicit material to a minor.

Both are facing significant prison time, although the exact amount will be up to a judge.

The boy is now living with his aunt and uncle.  You be the judge - what punishment fits this crime? Sound-off in the comments below.
