Hats off, for a moment. The premise of the Wild Mass Guessing section is that the theories offered are being taken seriously by at least one nutcase. This is what is known as a comedic premise. The theories are not meant to be serious. The entries are written as if someone believes them.
Of course, there may be sincere items sprinkled in, but they are more the exception than the rule.
If you are tempted to make an entry refuting a theory, the discussion pages are there for that. The article itself should be used primarily for tongue-in-cheek "proofs" and "evidence" supporting the theory, or for yet wilder theories; with that said, even dead-serious theories, the crazy-yet-scarily-accurate theories, and the out-there-with-no-basis theories all fit in WMG.
Don't remove theories just because they are Jossed or had barely any relation to reality.
Some folks have been missing the joke, so we've put up this programme note to make it clear. You may now put your Tinfoil Hat back on.
