I found something really cool that happens in Silent Hill 2 I'd like to share it scared the hell outta me cause I wasn't xpecting it.
You have to unlock the chainsaw first. when you have to run to the front porch beside the mexican restraunt to get the wrench. stand on the porch with the chainsaw and wait for a couple of seconds. Then James will mimic Leatherface fr Texas Chainsaw Massicure by swinging his chainsaw above his head and screaming..
Oh, I've seen him do that! I think he just does it after a while if you stand around doing nothing with the chainsaw equipped. I don't think there's any real special method behind it. >.>
It's pretty funny to see though.
