The ultimate betrayal

Last year I taught a full lecture class due to a reduced load for a new hire. This year that professor is teaching the class and when asked, I contributed all of my resources (notes, syllabus, ppts, exams).
I was ok with it.
Until, I saw the first lecture.
More than half the lecture is made up of my slides. Alright, whatever, if I had an issue with this I shouldn't have given out my lectures.

What bugs me is that the professor made one change and one change only.
They put the titles in Comic Sans.

NOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!
Anything but Comic Sans!!!!!!!*
Its characteristics are too casual for a lecture. It does not convey appropriate professionalism, let alone a first-class-of-the-semester-I'm-the-prof-not-your-buddy attitude. It conveys that your bake sale is for a really good cause. Or that your dance party starts at 8 pm sharp.

*Sorry for the rant if you love the Sans. I think it is great for a lot of things. Just not lectures. Or conference presentations. I had a labmate that used it (in turquoise-bold on a background of a watermarked field picture) for a conference talk. Red Phalarope and I all but threatened to disown her if she did it in her dissertation defense. She tried. We somehow talked some sense into her.
