We have the official list here people. Are you ready for this? The three official things that you can cry because of and nobody will give you shit for it according to my prestigious friend Jeff Allen (Supreme Visual FX Diety for The Matrix movies). Here they are:

1. Death of an immediate family member.
2. Losing a championship. (But for the love of God, don't do it on National TV)
3. Old Yeller.

And that's it. Anything else, take your chances.
