First comment of
The Futurama Theorem
You are lucky, we already read all of its comments !
And its first comment is the following
When I heard your rule around 2:30 ("once two bodies sit on the chair, they can't sit there again"), I was a bit confused with your phrasing: did you mean a body can't sit more than once, or just the PAIRING can't sit more than once. Indeed, as I kept watching, you meant the pairing.
