This is a game that’s great when you’re people watching and checking out the world while it parades by.

Just from visual appearance, you can give couples a percentage match. Anything over 60 percent is a good score, but the higher the better. Factors such as age, height, appearance, clothes, or anything else that’s relevant could all play a part in your score.

It’s obviously no reflection on whether or not they’re in love or a strong couple, it’s just an indication of whether they’re a bit of a surprising combination or whether they obviously go together.

Here’s a couple of celebrity examples to demonstrate how the game works, but you can play it with any couple that you see passing by as you ponder how the world works.

Lance Bass & Michael Turchin

  • A pretty good match.
  • Similar height, similar age, similar look.
  • I’m giving them a match score of 80%.
  • Why are they not 100%? Just from what I’ve seen, Michael seems to have a look in his eye that is a bit more edgy than he’s letting on. Maybe he’s holding himself back a little.

Neil Patrick Harris & David Burtka

  • They make a lot of sense together.
  • Similar height, similar age, similar look.
  • I’m giving them a match score of 90%.
  • Why are they not 100%? Just from what I’ve seen, I get a sense that David is dialling-back his sexiness so that he’s more in line with Neil.

Jesse Tyler Ferguson & Justin Mikita

  • On face-value, these aren’t two guys that you would probably put together.
  • The height difference, and the contrast in their looks are the main things. Neither of which are barriers to a successful relationship, but at a superficial level you wouldn’t normally pick it.
  • I’m giving them a match score of 60%.

Elton John & David Furnis

  • At a superficial level, this is a slightly surprising combination.
  • Different ages, different heights, and different attitudes. But their relationship obviously works for them.
  • I’m giving them a match score of 45%.

Tom Ford & Richard Buckley

  • Obviously, it’s the age-difference here that makes this an unlikely match. But they’ve been together forever and have built a successful relationship.
  • I’m giving them a match score of 30%.

Michael Kors & Lance Lepere

  • They look really similar in the face, but they’re from different generations which — combined with a height difference — makes this pairing slightly surprising.
  • I’m giving them a match score of 25%.
