As a dad-to-be, preparation for labour will usually entail ensuring the hospital bag is packed and your partner is feeling calm.
But for Reddit user Robin60062, it also includes getting a customised T-shirt to wear during your wife's labour that will very likely piss her off.
So while his wife was going through one of the most painful experiences in her life, Robin wore a top with his face on and the words: "I did this to you".
Just why?
At least some Reddit users seemed to find it hilarious.
