This comic is actually a re-imaging of an old comic that I always thought I could do better. The old version looked like this.
I wrote this joke entirely independent of the the "When life gives you lemons, burn life's house down" line from Portal 2. I believe Portal 2 came out in April, but I was abstaining from video games while I worked on my Mater's thesis through until September when I posted this comic.
Anyway, if you like this comic you can totally get it as a poster in my online store!
