I haven't been to a WWE show in quite some time, but what I gather from the OP is that they make you enter the arena through a scanner that indicates whether you are an "adult" or a "child". Immediately thereafter, these numbers are posted somewhere, so that threads like this can be created for our amusement.
WWE has always been PG. Stop treating it like the rule that it is TV-14 by nature. WWE was TV-PG before the "attitude era" and has been gradually returning to its old format since then. TV-14 is the exception, not the rule, and it's DEFINITELY not the cause of WWE's perceived failure to connect with its adult fans. PG WWE is not the same as WWE For Kidz (at least, it doesn't HAVE to be).
