The groom is trying to cope with the situation but he fails.
This footage was recorded at a Hungarian wedding. An invisible lady is singing a Christian church song about Jesus, who leads people through life, to the very end where he will open the doors.
It is not clear if the groom finds the song or just an entire situation so funny but he starts laughing and cannot control himself.
The bride first looks serious but after a white she also gets the laughing bug.
