Warning: this comic occasionally contains strong language (which may be unsuitable for children), unusual humor (which may be unsuitable for adults), and advanced mathematics (which may be unsuitable for liberal-arts majors).

We did not invent the algorithm. The algorithm consistently finds Jesus. The algorithm killed Jeeves.
The algorithm is banned in China. The algorithm is from Jersey. The algorithm constantly finds Jesus.
This is not the algorithm. This is close.
