Chris vs. Big Josh
I have made it clear to both Big Josh and Chris that they are not allowed to get into a drinking contest against each other. This is because NEITHER ONE WOULD YIELD. They would continue until one or both were dead.
I fear the same would occur if they began competing to see who has watched the Transformers movie more times. Big Josh does have the Autobots symbol tattooed on his wrist and considers Optimus Prime to be his only true father figure, but I wouldn't put it past Chris to already have a Decepticon emblem tattoo and not have told anyone about it.
On the nostalgia issue, I think The Brothers Grinn had some interesting commentary...
That, and pretty much all the comics on this page.
