The spirit of Christmas has taken over 30 Rock, and this week's Saturday Night Live host, Melissa McCarthy, joined in with a sketch about spreading joy through acts of kindness.

Well, kind of.

Following her young neighbor's heartwarming decision to shovel her snowy path, McCarthy — the elderly, seemingly innocuous grandma next door — decided to return the favor, with a series of gifts that escalate in terrifying, hilarious ways.

A bully (Marcello Hernandez) hog-tied on the front lawn, two women and a pimp on the doorstep, a gun in a nicely-wrapped box — it's like some kind of messed-up Grinch fable. Grandma might be a psychopathic killer, but her misguided attempts are still spreading holiday cheer.
