From experience I can tell you these sonograms that show what a baby looks like while inside a woman don't always produce the most convincing-looking images. Somehow a doctor is able to slide this paddle thing along the woman's pregnant stomach and know exactly what is what, but most of the time you're just sitting there, like, "Wait, that was an arm? Really? It looks like a head." Or you could be like this guy on Reddit who looked at his baby's sonogram image and saw the Spider-Man villain Venom, who you'll remember from the comics or Spider-Man 3.
Take a look:
Freaky. I'm sure the rest of the pregnancy should go swimmingly. How much would it be to rent Andrew Garfield to deliver the thing, I wonder?
