no need to get snippy with me, sir.
first of all, the person posting it said "I can't tell if this is serious."
so unless s/he was being sarcastic -- which is possible -- then it wasn't obvious to at least one person.
in any case, out of the 55 people who visited it, i'm betting at least a few were stupid enough to fall for it.
besides all that, it's an old link that's been around for a couple of years. some of us have even seen it before.
