While I freely admit to getting a kick out the goofy George Lopez hosted show “Take Me Out,” the “Bachelor Pad” is easily the most despicably fun reality dating show of the summer. And I mean that in the best way possible. This “Bachelor” spin off, which started its third season July 23, mixes bachelors and bachelorettes from seasons past with fresh faced newbies. It’s guilty pleasure viewing at its best. Or is it its worst?
