Jim Harbaugh is a total hustler.

The University of Michigan football coach gave some advice to trick-or-treaters in an interview with Detroit's WXYZ on Monday night. What does he suggest? Well, he says, two costumes mean you'll get twice the candy. 

That's right, Harbaugh thinks your kids should don two different costumes and hit up the neighborhood twice in order to bring home twice as much loot. I mean, that works out well for them and for you, right?

Here's what he had to say:

I try to advise them to get two costumes, to be go-getters. You can hit the neighborhood in one costume. Better to jog and to run from house to house, then you can get more candy than anybody else. Then come home, make a quick change into a second costume and go hit those same houses again.
