Panel one confused some people. It's just more exaggeration of how horrendous "KITTY!" was.
Of course, the rest of the comic also confused people, mostly because they look for deeper meaning than "Mr. Verres has bad handwriting and everyone interprets it as though it were for them." That's really all there is to it, and it's inspired by times I've had to interpret band handwriting.
