Data experimented with wearing what he described as "a fine, full, dignified beard" in early 2365. Data felt that such a beard "commands respect and projects thoughtfulness and dignity." His crewmates described his beard as being "very different", and were especially amused after Data began stroking it and inquiring whether such actions made him appear more intellectual. ()
