What happened next will surprise nobody who has followed the hockey career of the former NHL agitator.
Avery, who was preparing to make his off-Broadway debut in the play "Negative Is Positive," reacted poorly to the offer of a slice. He said "No," and apparently thought the assistant had called him an "a-hole" as opposed to simply offering him some food.
He went on a tirade and quit the show.
“He said I was ‘talking s–t’ and said I was ‘so full of s–t,'” the assistant stage manager, Natalie, told The New York Post's Page Six. “That’s when I realized that I was dealing with a madman.”
The play's director also caught some of the brunt of Avery's pizza anger. "Don’t you know who I am?!" Avery shouted at Andreas Robertz. "I think something snapped in him," Robertz told Page Six.
The aptly named "Negative is a Positive" is about an interracial married couple and Avery was playing the lead character's best friend. The show opens on Thursday with an understudy playing Avery's part.
"He's a playwright's worst nightmare," said the play's author Christy Smith-Sloman.
Perhaps Smith-Sloman should swap some stories with former Rangers coach John Tortorella if they're ever looking to put Avery on stage again.
