Below, five of our favorites so far. Get inspired: Perhaps you and your family can create your own this holiday.
1. Miss Piggy
In a brilliant commercial for The Muppets, Miss Piggy channeled Adele (wind-blown look and all) to let Kermit known how she really feels.
2. Ellen DeGeneres
Ellen got into the fun when the video first dropped, envisioning that she was the inspiration behind the iconic tune. Bonus: More than one old-school phone.
3. James Corden & Billy Eichner
Corden and Eichner get into the holiday spirit with some new lyrics -- and costumes. "I was wondering if after all these years you'd like to trick or treat," the duo croon with the same level of emotion that Adele has.
4. Key of Awesome
The viral-inclined crazy minds behind Key of Awesome's videos created one of our favorite parodies from non-celebs, this one also re-imagines Adele's lyrics, this time wondering just how crazy Adele sounds about her exes. No judgment!
5. Saturday Night Live
This isn't a "Hello" parody in the same way the others are, but it still makes us a laugh -- a lot. Bonus: Adele's super pointy fingernails getting their own homage.
