Idiots standing outside my office

Two of my coworkers are standing right outside my office in the doorway blabbing on and on about some trivial shit. Don't they realize they are standing right outside my doorway and I am trying to work. (Well I'm not really working however it does look like I am.)
I wish I could spray them with the Easy Cheez can that someone left in the kitchen. I'd fill their mouths up with the EZ Cheez and then clap their head and jaw shut so the homogenized cheez product would spray all over the other person. That would teach them and teach the person who left the EZ Cheez container out to never leave such an object that can be used for malicious purposes lying around.
