Absolutely no diss to Joeyess, it was a grand idea. BUT, from Salon-
McCain has himself described having an adverse reaction to the sound of jangling keys, which reminds him of his Vietnam jailers. McCain also told doctors that during solitary confinement he had strayed pretty "far out" and had referred to himself as "mentally deteriorating."
It could be and would be interpreted as teasing or mocking McCain's PTSD.
**I'm going to take a presumptuous hit on this and say I can't and shouldn't tell people what to do or not. But I cannot see any good coming out of this. Joey had a brilliant idea that stands alone. He had no knowledge of this fact and cannot be faulted. If we want to use this as a springboard to discussions of McCain's PTSD issues, IMHO that would be the way to go.
