This one isn't exactly a "guest strip," so it needs a bit of explaining. Zap! (an excellent comic, check it out. Now. Go.) is written by a guy and girl team. Someone made a comment on their forum about imagining the guy being stressed and manipulating the girl like one of those squishy "stress balls." (It's in the "Hum and a Reward Pic, What Could Be Better?" discussion, if you want to read the whole thing.) An image flashed before me of the moment after, but instead of the creators it was between the two main characters of the Webcomic itself. I drew it up as a single panel to post in their forum as a quick chuckle. It's not particularly amusing out of context, but if I don't post it y'all are likely to think I'm slacking, so... here. Now, go read Zap!
