Could you use a nail gun to nail someone to the floor??

Don't freak out.. I am writing a book and need to know if it is feasible to nail a person to the floor with a industrial strength nail gun. I asked a construction guy I know and he turned just a bit pale. HAHA and forgive me.. I could not, for the life of me, figure out which category to put this.
Update: great answers.. but some of you really need to chill out.. it's ONLY a question...and the book IS fiction, for heaven sake! Trust me, there is no need for concern on my behalf.. my Karma is wonderfully positive..
Update 2: Thank you all for your answers.. I have regular sources for most of my research questions, but this one fell outside that sphere.. can't IMAGINE why! Thanks again.
