Humans have the most bizarre mating rituals of any creature on the planet...

[Mister Obvious]

Unquestionably, by far, hands down the weirdest, strangest, most bizarre.

This must be very entertaining to any observers. 

I would say they probably consider it a mixture of funny, sad, and endearing.

[Mister Obvious]

Because you know it's totally not sexy to the observers. It would only be sexy to us because we're humans.

Like... do you think squirrels feel sexy?? We'd never see them as such, no matter how sexy they feel. We'd just think it's funny.

And it would just be funny or cute with humans too... except that we are so perverted and violent, what with our wars and enslavement of one another. We are not like the other animals, and the differences are most certainly not a source of pride.

Our only saving grace will be to care for the planet and the other animals.
