Watching two married guys hit on a single woman is like finding out Santa Claus doesn't exist.
If you're female.
Marriage is an institution and a covenant and whatever, but it's also an idea. And we all know how ideas don't necessarily formulate. Especially in LA:
"Hey, I have an idea about a show for ABC Family about a guy and his dog and the dog tries to help him find a woman but..."
For a guy, it's not surprising. Our dick often takes the reins and will take us on journeys beyond our wildest dreams, regardless of who we're invisibly bound to and whether or not we wear an iron circle on our finger. The government may say one thing, our heart may say one thing, but our biology says another -- something we regret after the initial nut-busting (until we're ready to fuck again).
Because while we can speak and think and make money doing a job we never wanted to do, we will leave the conference room to grunt, shit, and enjoy the smell like we never thought we'd do.
