With an application like that he would move to the top of my "hire immediately" list! Anyone who would fill out a job app like that deserves the job. That is my kind of employee.
I would like to talk to him before hiring him. Donno how it goes where you are situated but here whe first have a written aplication, then a verbal aplication and sometimes that is in rounds. It depends if they have more people wanting the job.
I'd hire him just to keep him around me. If someone has that amount of humor, if i was going to "kill" someone at work, he would say something and I would forgive the person instantly.
