13. Baby’s Ticklish
Anyone who is ticklish can immediately relate to Jennifer Grey having uncontrollable laughter during the scene where Patrick Swayze runs his fingers along her armpit. It turns out that this was another example of unscripted movie making. Apparently Grey really did have a giggle fit and she couldn’t regain her composure no matter what she did. If you remember, Johnny was actually quite annoyed in the film and that was an organic reaction too. We assume he felt it was just too unprofessional, but either way it’ll go down in history as an iconic scene.
