iLrn (circa 2000) was a form of cruel and unusual punishment practiced by various universities around the US, similar to that of maple and matlab.

The online homework program utilizes a unique "insanity" factor by repeatedly telling students they are WRONG in large, red, bold letters, even when they answer a question right.
-Hey did you go that iLrn homework?
-Nah, I just went to the store for some rope and tied a noose instead.
