The memes faces were a later addition. The show started with a cute and cartoony style (S1) then changed into a stiffer, a bit less expressive yet still good looking style (S2) and then changed again into an even less expressive style that didn't use forces faces (S3). It was the four season the one that started this trend and now the writers and the animators of the show think this shit is an essential part of the show. Damn, the new opening starts with a giant meme face.
