Quote from The 'Burbs

(Ray and Art are in Ray's backyard, and Ray's dog Vince has brought Art a bone to throw. Art grabs the bone and does a double take.)

Art: Do you know what this is?
Ray: It's a bone.
Art: It's a femur.
Ray: It's a femur bone.
Art: A femur just happens to be a human thigh bone, Ray.
Ray: Wait, how do you know that?
Art: Biology 101. I mean, look at the size of this thing! You think this came off a chicken or something? Where the hell did Vince get this?
(Both men slowly turn and look at the dirt where Vince pulled the bone out from the other side of the fence)
Ray: He dug it up from underneath the fence.
Art: Ray . . . Ray, there's no doubt anymore. This is real. Your neighbors are murdering people. They're chopping 'em up. They're burying 'em in their backyard. Ray . . . (raises bone up in front of them) this is Walter!
Ray and Art: NOOOOOOOOO!! AAAAUUGHH!! NOOOOOOOOOOOOOOO!!
