Guys seriously let's stop, it's 2 numbers who just so happen to be placed right beside each other in the number sequence, so your gonna see them a lot and truly nothing is special about it...

I highly doubt registration services have the humor or time to deal with such memes, this is more likely your confirmation bias, those are 6 and 7, not 67, i.e. different numbers and it's the most normal way to write these two numbers out. You're interpreting meaning into something that does not have any meaning in that regard.

67 are just numbers that have existed before the meme, so… xD
