Gav: This poker game is ruined. I have nothing unrepressed against you Cecilia, but you have to leave. You're strictly "Tier 2"
Cecilia: What?

Gav: The more players, the better, but to play seven-card games with a 52-card deck, we cant have more than seven players. Your presence makes eight.

Gav: Only those friends we can trust to show up are initially invited. They represent the top tier. We invite you "Tier Twos" only if a "Tier One" can't make it.

Cecilia: So...what? I don't get it. Are you running some kind of pyramid scheme?
Gav: Several, but that's unrelated.
