Pearls Before Swine by Stephan Pastis for March 18, 2014
Rat: What are you doing, Pig? Pig: Building stuff with my new erector set. Normally, I don't like these things 'cause it's so hard to disassemble what you build. But this one automatically breaks apart after you're finished. Rat: It's that convenient? Pig: Yeah. Though it does come with a warning. Rat: What's the warning? Pig: "See doctor for erector buildings lasting more than four hours." Censor: Proud of yourself? Pastis: Hardly.
