Bob and Sarah are a physicist and chemist, respectively. They should have known better than to send us mad libs for an RSVP card.
Translation: On July 23rd, Bob and Sarah will finally be elements of the set of unordered pairs of people. Kyle is very (the official sequence ID of the “happy numbers”) for them, and wishes them an uncountable infinity of happiness and that they should be an ideal example of the wedding ring together. Therefore, 1 will, with less than 1 percent conformance with the null hypothesis, attend and look forward to seeing the undefined (as bride/groom is indivisible) in their Klein bottle dress/suit.
