Five Second Rule

"Five Second Rule" is one of the clips bundled in the Inside Out home media release, acting as a "deleted scene" of sorts, even though it's not an actual deleted scene. Its main character, as stated on the title card, is Disgust.

Plot
The clip opens with Riley eating grapes at the park. She throws one of them up and attempts to catch it in her mouth, but the grape falls on the ground and starts rolling away. Riley gasps.

Inside her mind, Joy quickly announces the "five second rule": namely, if Riley can catch the grape within five seconds, she can eat it. Then, Fear starts calling out numbers as Riley rushes for the grape, and she succeeds. Joy is about to eat the grape, when she is confronted by Disgust, who will stand by the fact that since the grape touched the ground, it is inedible. Joy and Disgust continue fighting, reflected on the outside with Riley having second thoughts about eating the grape. It is only with some well-placed disgusting imagery that Joy can shoo Disgust away, then make Riley eat the grape.

In parodies
"Five Second Rule" is yet to be used in any Inside Out parody.
