Pair programming just seems creepy. I can't even read when someone is looking over my shoulder. You might as well be sticking your finger in my face just far enough away so we're not touching. "Two sets of eyes are better than one," may work in the field when you're on stake out looking for the enemy, but in programming I don't really see how that translates. Aren't bugs caught in the code-review process?

Eliminating bugs up front is like asking human beings to be perfect.

In other words, good luck with that.
