Big penis stomach anatomy fail

I know that people used to get a lot of things wrong. Age of the earth at 6,000 years, or the "sun goes around the Earth." I mean, you look around, you see stuff, it just looks like that.

But when a series of Jesus pictures based on medieval art styles shows the ancients couldn't even get basic anatomy right by making abs look like a giant weiner - I mean, did people in Ye Olde Times not even know what *people* looked like?

Personally, I think the original artist was having a laugh and nobody else got the joke.
