Best Guest Coach: Alanis Morrisette
The funniest recurring motif on the show this season involved the testimonials during each battle round episode; when contestants would always, always give some variation of the phrase, "I walked into the room and there's Robin Thicke. Did I die and go to music heaven?" The guest coach who was most worthy of such excitement, though, was definitely Alanis. She delved deep into psychology, asking contestants if there was a range they were scared of breaching. She also memorably gave contestant Karla Davis an alter ego named Bertha: "the big girl who lives inside you."
