This Star Trek: The Next Generation t-shirt features an image of the Ferengi scientist Doctor Reyga. The shirt reads Ladies' Man. The Ferengi were a warp-capable humanoid species from the planet Ferenginar. The Ferengi's most distinguishing feature were their large ears which gave them extremely acute hearing. Ferengi lobes were also said to tingle whenever the Ferengi sensed an opportunity for profit or was sexually aroused. Whenever their ears tingled, every Ferengi became a ladies' man.
