I remember various pictures making jokes about bad anatomy in art, but can't find anything now.

1. Disproportionate bodies with sagging hips (removing perspective and straightening bodies with wrong anatomy).

2. Detailed complex shading of badly drawn pictures.

3. Different views of incorrectly drawn muzzles.

4. Numerous tutorials about popular anatomy fails like anus position.

Any pointers? Tags maybe? All relevant pictures are welcome.

Perhaps those jokes were actual critique and the posts were deleted because of bad anatomy (does not meet minimum quality standards)?
