Melissa McCarthy mocked "The Favourite" in probably one of the wackiest costumes to grace the Oscars stage.

McCarthy walked on stage with Brian Tyree Henry, who also wore an early 18th century gown, to present the best costume award.

Her dress was dotted with stuffed bunny rabbits — an homage to the main character in "The Favourite."

As McCarthy presented the award, she performed ventriloquism with the rabbits.

"These artists create a pastiche of textiles with authenticity, yet never distract from the story. Costume designers construct the looks that ground a character to a particular time and place in the subtlest of ways," McCarthy said.

It was a strange bit, but it brought plenty of laughs.
