Bonom - 27

There are different ways to read it :
- Bonom is talking to Bonom in the panel under, about the bonom in the lowest panel, who finaly disappear, which surprise him (in the seven's panel).
- You can also see it as a conversation between neighbours in a building. Then it becomes almost an abstract composition that you can read every directions, more an illustration than a comic.

I agree this gag is not easy to understand. Actually I like every one to get it (or not) is own way.
