Melissa McCarthy takes the Christmas spirit too far in SNL sketch

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.
