I dare Jack to pretend to be a ghost for a night and scare (more like a heart attack) Merida.
Jack:-whispers-Hehehe...My God,shes gonna scream so loud...Just gotta put on some makeup...
Merida:What?
Jack:Nothin' ! -runs to bathroom and puts on makeup-
Merida:Weirdo.Whats he up to?
-an hour later-
Merida:Jackie!Where are you?It's like pretty late and we need to sleep!But well,Jack don't need to sleep since he's dead...Jack?
Jack:-comes out from behind with a bloody face and says with a ghostly voice- M-me...ri...da...I am coming to get you....
Merida:-looks behind and screams-AAAAAHHHHHH!-starts hitting Jack-
Jack:Ow!Stop!Stop that!
Merida:JACK?You're so dead,grampa...-grits teeth and takes a wooden bat-Ready to play snack the 'ghost'?
Jack:Oh crap.
