Tell me about the most insane over the top coworker you ever had to deal with ??

had a guy i once fired supposedly call me from a bridge. said he was gonna jump and that i shouldn't have fired him. he hung up and i called 911. he called back and asked to talk to one of the other guys. he talked to him. hung up. all the while i was on phone with 911. he then called back and said he was gonna eat glass...it sounded like he did...he hung up, called back and wanted to talk to the other guy...he told him to tell me he was drinking alcohol with his mom at home...the glass crunching sounds were ice cubes....what a nut he was
