Your challenge will qualify until you find the one person whose parents have taped every time they had sex and can provide the dates on said tapes. You may want to watch out, because now you never know when you might start having to provide evolution tapes :P
Of course… that would imply the person had watched their parents sex tapes, so you’re probably still very safe.
You still can’t know that they taped themselves every time they had sex. Now can you know that either of them might have had sex with someone else that wasn’t taped.
