No one-liner joke

Mentally ill deaf man with stomach problems goes into a convenience store bathroom.  An hour later, he’s still in there (later, the family explains “he needs extra time” due to his stomach problems) and the cops are called.  They start banging on the door and shouting, which he can’t hear.  They get a crowbar and start trying to force their way in.  He thinks The Devil is coming to get him.  They break in, he pushes them, they push him back.  They pepper spray him, but then they see his weapon: an umbrella.  The Tazer comes out and they shock him three times.
