Today’s Jesus and Mo strip, called “drugs” is based on a Daily Mail report on functional magnetic resonance imaging (fMRI) of the brains of 19 “devout Mormons” (what—no other faiths?). When the Mormons were scanned while undergoing religious experiences, like reading scripture or watching Mormon videos, the fMRIs (which show blood flow to various parts of the brain) revealed activation of several parts of the brain, notably including the “nucleus accumbens”, a bit that also lights up during hedonistic experiences like taking drugs or listening to music. (You can read the paper in Social Neuroscience here, though I haven’t done so.)
At any rate, Jesus is willing to see how other stimulants affect him, but of course Mo is forbidden from drinking or listening to music. My suspicion is that Jesus’s “drug”, which appears to be a Guinness, isn’t strong enough.
