I just want to say that this strip has more speech bubble pointers with two non-vertical sides than any other so far. Those things are a pain to do.

You might have noticed the speech bubble pointers nearly always have one vertical side. I do that because flood-fill misses the anti-aliased pixels on the inside edge of diagonal lines, so I have to fill them in by hand with a paintbrush tool. Doing that along two edges doubles the work. I tried increasing the flood-fill tolerance to try to get the anti-aliased pixels once, and ended up colouring the entire strip.
