Yule Be Sorry (Pinky, Elmyra and the Brain)

A second Christmas cartoon starring Pinky and the Brain was done for the series' continuation, Pinky, Elmyra and the Brain, when the mice were adopted by Elmyra Duff from Tiny Toon Adventures.

Synopsis
In a twist on the It's a Wonderful Life story, Brain wishes he never met Pinky. He then has a dream in which Acme Labs was never destroyed, but Elmyra is still tormenting him there instead. When he wakes up from this nightmare, Brain apologizes to Pinky for his outburst.
