Incomplete numbered groups.

1. The Self Referential Six (Rick and Morty): excluding and Imprisoning Rhett from the group for supposedly being very dangerous.

2. Uno, Dos and Cuatro (Ferdinand): they don't want to talk about Tres.

Sex Pistols - JoJo's Bizzare Advenure

They're numbered 1-6, but with a 7 instead of a 4, because Mista is really superstitious about the number 4

[u/NeverMore_613 → u/Yanmega9]

I know that the Chinese glyphs for 4 and death are either the same or very similar, I wonder if it's something similar (or a direct borrowing)

[u/Gaelic_Gladiator41 → u/NeverMore_613]

I think it's a general old superstition in East Asia, same way the west has 13

[u/Howlett92 → u/Gaelic_Gladiator41]

Which is funny because Mista is Italian.
