As evidence, he pointed to an ‘‘incredibly offensive song that upsets a lot of actresses in the audience.’’

With that, a pre-taped production number featured MacFarlane singing ‘‘We Saw Your Boobs,’’ saluting a roster of actresses who have bared themselves in their films.

But then, in an effort to atone, MacFarlane sang a classy rendition of ‘‘The Way You Look Tonight’’ accompanied by Charlize Theron and Channing Tatum in dance.

Not good enough, said Shatner, who then revealed a video clip where MacFarlane, costumed in a Flying Nun habit, hit on Oscar nominee Sally Field in the green room.

Back and forth went the routine: Bad Seth and Good Seth. Both were very funny, stewarding a broadcast that never went askew.
