I haven't seen this posted before, probably because the movie isn't exactly well known, but in the movie Born (2007) Alison Brie gets tickled by her friend. The only place I've been able to find this scene is in this video of a dude reviewing the movie, at 6:43. youtu.be/dzN1i35NvGM?si=v688I3x_SWozYMJK
