don't take the screw out

so today we were on division filming jerry's dialog project - chris was the priest and galvin was johnny something or other. jerry always likes to do films with killing and priests and gangsters... so we're on division with a gangster and a priest and our film junk. galvin's parents came in from bend and met us on the street. we're standing there talking and this homeless guy comes and sits in this rocking chair that's outside of the store we're in front of. all of a sudden he says 'hey, are you roman catholic?' chris says 'no, i'm not, i'm just dressed like this for a student film we're doing' and the guy says 'can i talk to you padre?' and chris says 'i'm not a priest' and the guy says 'i know, but can i talk to you padre?' and we're thinking he wants to have confession right there. so chris walks over to him and he says 'i have something for you' as he reaches down towards his belt, lifting his satchel. he pulls out a neon green, plastic gun and holds it out towards chris. 'i want to donate this to your church' he says. chris takes the gun, thanks him and quickly walks away from him. the man says 'don't take the screw out.' 'what happens if you take the screw out?' i ask. 'you'll have to reload it' he says.
