I'm looking for ecchi shots. However, there's a catch. It has to be at the most inappropriate moment. It doesnt necesarily have to be extreme, just has to have an inappropriate timing.

Best example so far

Thats a grenade on her chest. It took THREE pages to show this off to the reader, and I just laughed.

Can any of you share?

Kumagawa: Ahem, Good morning to all the minor characters.

I sadly don't have any examples, but that link just made me laugh so hard. Especially the page after that, when the grenade just bounces off her boob LOL.
