I reckon ghostface should stick with a knife but upsize it... so he would kill the first victim with his normal knife but then he finds a bigger one and picks that up and drops his old one.... if you can picture it, it looks kinda cool!
P.S. I'm back (obviously)
Randy: never, ever, ever under any circumstances say, "I'll be right back." Because you won't be back.
Stu: I'm gettin' another beer, you want one?
Randy: Yeah, sure.
Stu: I'll be right back!
