When my wife was about to have our first baby, we brought a tape recorder to the delivery ward to capture the sounds of the birth, the baby’s first cry and our doctor’s voice saying, "It’s a boy!" or "It’s a girl!" We intended to use the tape as a fun message on our answering machine to help announce the birth to friends and relatives.
My wife’s labor went relatively smoothly and, when it seemed appropriate, I inserted the blank tape and began recording. Shortly thereafter, our baby was born and we all heard the first cry. The doctor held up the baby and, with tape rolling, loudly proclaimed, "Wow, will you look at the scrotum on him!"
