Craig Calcaterra's wife
From Wiki Gonzalez
In some thread long ago, shortly after Rick Reilly asked Sammy Sosa to pee in a cup for him to prove he wasn't on 'roids, Craig Calcaterra made an analogy. He said that if Rick Reilly came up to Mrs. Calcaterra and asked her to have sex with him, and she were to refuse him, that would not mean she was against the concept of sex altogether, just sex with Reilly. Some primate then posted as Craig's wife claiming to be sexually frustrated because her husband was ignoring her so badly. Craig responded to the fake-wife by claiming "Honey, how can you expect me to do that when there's still VORP to be calculated?" People just piled on from there. Voros McCracken may have been one of the people posting in that thread as Craig's wife.
From there it caught on as a primer joke for a while. Craig even told his actual wife about it, and the real life Craig's wife did post there once. Nobody believed it was her.
Craig posted less frequently later on, supposedly because he and his wife were busy trying to conceive a child together. Or with Rick Reilly. It depends how much VORP still needs to be calculated.
