Ghost of Whitney Houston

In Big Mouth, the Ghost of Whitney Houston appears to Missy Foreman-Greenwald as a glamorous, no-nonsense spirit guide, popping up in mirrors and bedrooms to dispense affirmations, tough love, and pop-diva flair. She wants Missy to find her voice and own her identity, and she is not shy about saying so.

The joke is the mismatch: an actual icon reduced to hallway-locker pep talks, and Maya Rudolph plays it completely straight, all runway poise and vocal runs, which makes it funnier and somehow more moving. She becomes a genuine source of warmth for Missy rather than just a celebrity cameo gag.
