A recent YouTube video shows the father of four girls fainting when he finds out his wife is pregnant with a baby boy.

According to WGN, the couple had asked their doctor to write down the baby’s sex and put it in a sealed envelope until their gender reveal party.

They planned for the baby’s gender to be a surprise at the party, so when they cut open their cake and saw that the inside was blue — the dad got so excited that he fainted.

He quickly recovered, but said he was in shock.
