Fair enough, I respect the candor to speak one's opinions even if (or especially if) worried that they may not be popular. I certainly don't want to hurt anyone's feelings. But if you worry about offending anyone with a joke, then you're basically not allowed to say ANYTHING because pretty much EVERYTHING will offend someone online. There are whole constituencies of humanity that exist for that sole purpose.
But this is an IM fan message board. I suspect a lot - if not most - of us enough are past mid field and have spare tires around our bellies.
And there's nothing wrong with having a laugh about that, and we should not be cowed by an online scolding.
