Why everyone adds "Merry Christmas ya filthy animal" at the end of Film?

The line “Merry Christmas ya filthy animal” derived from a parody film, in the Home Alone Franchise. This is a Christmas movie and is also a reference to the popular movie Home Alone 2. This was gone in New York and released in 1992. The hero Macaulay Culkin is a young child who comes to the wrong city instead of Miami mistakenly, where his parents and family are waiting for him on Christmas vacation. This movie was more interesting than the Home alone, in which the Macaulay was accidentally left by his family at home. His family moved to Paris for Christmas.

Some Popular Scenes in Home Alone

 The scene of the film starts with the dead winter night in the wild building in Winnetka. At the distance of 20 miles north of Chicago, an actor named Michael Guido sitting on his knee, wearing a fedora and trench coat; he is in the tense condition because an older man is pointing him via gun:

“I am going to give you the 10 to get yellow, No-good, ugly keister off my property before I pump your greedy Guts full of clue”

Guido replied to him while stepping away to him:

“Johnny, I am sorry, I am going”.

As the movie continues the sound of fire is heard and all crows are flies at a time with ca-ca voice. Angels with Filthy Souls is the pretended criminal movie that is put into the Chris Columbus family and beloved John Hughes comedy Home Alone.  It was prohibited to Kevin who was 9 years old to see the gangster movie but he watched the movie and asked friends to stop him doing so. It was a horrifying condition for him but at the last, he used a weapon against the Wet Bandits.

The Sequence of the scenes was managed beautifully and attracted the public as well. All the interior shots in Home alone including all scenes in the MC family home were shot on the New Trier West High School Gymnasium. The full set of the movie was made up of just a couple of walls.

The office of Johnny was decorated mainly for full dramatic backlighting. The office contains the   pebble surfaced luminous glass on the door and has a Palladian window that sprinkles the spotlight on him at his desk through Venetian shades.

“Angels” film was created in the contrast of the Home alone but it is not a real movie. The whole movie is based on the man who is the head of the gang and one man has given a huge loan to him. The Gangster told another man to owe money until he counts for 10 before shooting him. Head of the Gangster shoots the man saying “Keep the Change, Ya filthy animal”. In Home Alone 2, Kevin finds the effect of filming Angels. In the Angels this same scene was included with the same gangster man, but this time, he shoots a woman and ended the scene with the words saying: "Merry Christmas, ya filthy animal" and Happy New year.
