I saw these panels in Oral Cavity Infectious Syndrome by Kago Shintaro and thought it would be great to see more of similar stuff. Not necessary manga, maybe pictures or animation. Haven't seen on yuri yet.
Anyone?

*remembered that flash parody on death note.

Sorry for bumping an older topic, but this made me think of this manga:

Mousou Shoujo Otakukei is basically a parody on yaoi fan girls who fantasize about their straight classmates being together.

Also, I hear the OVA Puni Puni Poemy is a yuri parody of a few anime, mainly Excel Saga. People have also made connections to Card Captor Sakura and Sailor Moon. I have been told it is stupid funny so that means some love it and others hate it.

I have yet to test either, but I will someday. ...Maybe.

You're Lovelier Than a Rose is a parody of the tropes of yuri, and especially those of Maria-sama ga Miteru.
The entirety of Maria-holic is a similar parody.
