Witzelsucht and moria are time-honored neurobehavioral terms. Witzelsu
cht is a tendency to tell inappropriate jokes, and moria is euphoric b
ehavior. Focal right-orbitofrontal parenchymal lesion is often the ana
tomical substrate for these behavioral attitudes. This case report pre
sents a patient with a longstanding witzelsucht-moria behavior. Single
photon emission computerized tomography (SPECT) showed hypoperfused r
ight-frontoparietal area in the absence of structural damage.
