The episode “The Quality of Life” opens with a friendly game of poker. Upon noticing that Geordi is growing a beard, Beverly confesses to having a thing against beards; she finds bearded men suspicious. When the bearded men at the table protest that beards are a proud symbol of strength, Beverly rolls her eyes. “It sounds to me like you feel beards are nothing more than an affectation,” Geordi accuses.
“I do,” Beverly confesses. “But there’s nothing wrong with that. I mean, women wear makeup and nail polish. I just think it’s time you men admitted it.”
