Grant (On Ghost Hunters): What the frig?
(On the show about the Stanley Hotel)
Grant: Yeah awesome as long as Jay doesnt go crazy with a axe.
Grant (At Lisheen Ruins in Ireland): We had to have Dustin go in and shovel out all the cow patties.
Grant: We got to the bottom of a few things, but not everything.
Grant: There are claims of apparitions and fairy activity. And not fairies like you picture with wings and pretty little dresses and crap. I mean, these things are feared by the Irish and respected by the Irish. And not necessarily friendly by any means.
Grant: I just put in a bathroom for somebody, now I get to go and search for ghosts.
Grant: (On Ghost Hunters, after hearing a noise) It's you, you stupid cat. Your nose whistles.
Grant:(On the show)
We knew we were putting our lives out there and people were going to love us or hate us.
Grant: The thing with that, Brian, you've got to make sure you stay true to who you are.
Grant (On Brain's romantic relationship):
It's funny, because she wanted you to quit the show, then when you did, it's like, "Oh, you're not Brian from 'Ghost Hunters' anymore." Right now, Brian is "Brian on "Ghost Hunters " and it's going to be hard to find someone who appreciates him for who he is, not the guy who's on the show.
