 This comic shows a billboard erected by a neuroscience department in an attempt at sabotaging a rival department's volunteer subject compliance with their fMRI study instructions, by suggesting behaviors which would likely produce unexpected results, such as recalling a frightening memory after seeing similar stimulus slides, or imagining the lab technician is a romantic interest when reading words that begin with the same letter as their name. This is funny because academic department rivalries do not usually lead to sabotage,{{citation needed}} and in the rare cases when they do, it's usually clandestine instead of so absurdly blatant. The comic also shows neuroscience in terms of the technologies used to study it, and how experiment instructions can influence its development.

 Following such suggestions or even inadvertently remembering them during an fMRI could very well interfere with its results. fMRI experiments are often criticized because they have low {{w|statistical power}} and can easily be confounded by experiment subject error in following instructions, among many other variables. In a famous 2009 study, a dead fish was shown to have apparent evidence of brain activity when scanned with ordinary fMRI techniques.[http://prefrontal.org/files/posters/Bennett-Salmon-2009.pdf] In 2015, discovery of a statistical error invalidated at least 40,000 fMRI studies.[https://www.sciencealert.com/a-bug-in-fmri-software-could-invalidate-decades-of-brain-research-scientists-discover] Subsequently in 2017, many more fMRI results were further discredited due to poor software parameter selection.[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5487467]

Alternately, the instructions on the other side may be intended to disrupt research in the other institution.
