10 Movies You Didn't Realise Had Post-Credit Scenes
6. Monsters Inc.
Another Pixar movie on this list, Monsters Inc. includes a bonus scene for fans after the credits have rolled that rounds out a funny minor plot point from earlier on.
When Sully and Mike are trying to get Boo back through her door, they have to distract the other workers by pretending they are rehearsing a musical. The two are forced to sing a song that they have made up on the spot, titled "Put that thing back where it came from or so help me!".
The post credit scene shows Mike and Sully performing their bogus musical to the other Monsters Inc. employees in a big theatre production. There are multiple songs, tickets and a full set of extras and props.
The scene rounds out the lies that Mike and Sully had to invent and it results in an entertaining performance for two different audiences to enjoy, the one in cinemas and in the theatre.
