1. Brent's been sick this weekend. It appears he as an unreliable immune system and his students have a lot of germs.
2. The copy editor in me feels like I need to acknowledge that the past two comics have featured elliptical statements that actually require commas to be grammatically correct ("Interrupting their speculation, two policemen arrived on the scene..."), but what do you with with a comma when you use ellipses? To which panel would it belong? So...I left it off. I just thought we should all acknowledge the lack of a comma, and I'll do my best to not do it again.
3. Brent's got another periodic comic called "Alien Advertising," and its characters need names! Suggest them in the post right below this one.
That's all! Thanks for reading!
