What are some things you should never do/say at your wedding?

Have sex with someone in the wedding party, or the bride/husband's family at the reception

get caught cheating with a member of the groom/bride's family or wedding party

say the wrong person's name during the vows
not show up at the wedding at all

Cheat on your new spouse or say horrible thing like "I don't love you anymore/I want a divorce/I'm calling it off"

Kick your cake over and say it's not good enough for you.

If you're a male, then say "I'd like to thank Google Translate for helping me understand my wife."

If you're a female, then exclaim as loud as possible "I'm pregnant? HOW DID THAT HAPPEN!?"
