Bath Mat

Bath Mat is exactly what she sounds like: a household bath mat, given voice and personality in one of the show's stranger flights of anthropomorphized fancy. She turns up as an object of sudden, inexplicable affection, offering warmth and comfort with a sultry, inviting purr that makes the joke land before anyone has to explain it.

The gag only works if the voice fully commits, and Maya Rudolph does — she plays a bath mat with the throaty, seductive confidence of a genuine love interest, never winking at how absurd that is. It's a small, disposable bit elevated entirely by performance, the kind of throwaway Big Mouth turns into a highlight through sheer vocal conviction.
