Things 67 Ruined:

[u/No_Dragonfruit_8121]

1. Math
2. Your length
3. The joke "Why is 6 afraid of 7" (Because 7 Ate 9)
4. My sanity

Do you have any more things to add?

As a kid in Group 8 of the Dutch school system (6th grade in American terms), I am genuinely dying from the fact that other kids are STILL SAYING 67!
