If Sid and Stephen's bathroom looks familiar to you, it's probably because this set was also used for the memorable "Zeke's lab" sequence in FOMS, my first photocomic. Or it might look familiar because you've actually been in my bathroom in real life. That category's probably larger.

All of you should read Gottlob Frege's writings. Most of you probably won't care about them, but that is more of a defect in you than in the writings.
