From: Home Alone 2: Lost in New York
Genre: Movies
Who said it?: “Johnny”
The story behind the quote: Thanks to thegreatiaino for the huge correction regarding the movie as noted in the comments section below.
The quote comes from Home Alone 2: Lost in New York. The first Home Alone movie was very successful and it actually spawned two more feature length movies as well as two made-for-TV films. However, this was the only other film to feature Kevin McCalliseter (portrayed by Maculay Culkin); the other films featured a different family and a different kid. Also, Home Alone 2 is the only movie in the series that didn’t take place in the protagonist’s home.
The quote comes from, apparently, a mobster film called Angels with Even Filthier Souls, which is the sequel to Angels with Filthier Souls, a mobster movie that Kevin was watching in the first Home Alone. Johnny, the head mobster, accuses a woman of cheating with other men. Kevin uses this scene from the movie as a distraction to escape from the hotel staff.

Everyone recognizes that saying in the movie ‘Home Alone’. It’s a hilariously funny story about a boy who accidentally leaves his parents and siblings to travel to Europe on Christmas holidays
This is incorrect. The gangster movie in Home Alone 2 is Angels With Even Filthier Souls, a sequel to Angels With Filthy Souls, which he watches in the first one. In the first one, the quote is “Keep the change ya filthy animal”, not Merry Christmas.
