What television shows have instances of infidelity?

I am looking for a pretty specific clip of infidelity from a television program. However, the infidelity must have been committed by a man. I am researching this, but I don't watch too much television.

What television shows DONT have infidelity in them these days.

Too many of them have that mess. Don't know how/why that would even be considered "entertainment," but to each his own. Some people get their kicks from being exposed to such deceit. Looking for one in particular? just turn your TV on and you're guaranteed to find one.
