Original: The plan was executed when the match referee , Earl Hebner , under orders from McMahon , called for the bell to ring and ended the match as Michaels held Hart in the Sharpshooter submission hold ( Hart 's signature finishing move ) , even though Hart had not submitted .
Simplified: The screwjob happened when Hart 's opponent , Shawn Michaels , applied Hart 's own finishing move , the Sharp Shooter and then WWF Referee Earl Hebner called for the bell under Vince McMahon 's order even though Hart had not submitted ( or tapped-out ) .
