Last movie or tv series you watched?

A Charlie Brown Christmas.

Both that and The Grinch were done by former Warner employees after the closure of the theatrical cartoon division. Director Chuck Jones did the Grinch and Bill Melendez who had worked as an animator for Robert McKimson's unit did A Charlie Brown Christmas.

And being the cartoon manic I am I followed it with Looney Tunes:

Fast and Furious (first Coyote and Roadrunner), The Rabbit of Seville, Homeless Hare, High Diving Hare and The Grey Hounded Hare.
