Yes, the ugliness of the Human was not an exaggeration!
~ Tarr, seeing humans for the first time.
Tarr is a villainous Ferengi from the Star Trek: The Next Generation episode "The Last Outpost". He was the first Ferengi seen on screen in the Star Trek franchise. Tarr was played by Mike Gomez, who would later play the auto circus police officer in The Big Lebowski.
By 2364 Tarr had reached the rank of DaiMon in the Ferengi fleet, and commanded a D'Kora class maurader. Finding a T-9 energy converter at an automated Starfleet outpost, Tarr and his crew decided to steal the generator for their own purposes. Hotly pursued by the USS Enterprise-D, both ships were trapped by a guardian of the Tkon empire on a planet in the Delphi Ardu system. Believing the Ferengi had deployed an advanced weapon against them, Captain Jean-Luc Picard contacted the Ferengi ship to offer surrender. Learning that Tarr's ship was just as incapictated as theirs, Picard withdrew his surrender and asked Tarr for visual communications. Tarr agreed, and it was the first recorded time that a Ferengi and human saw each other. Tarr was not impressed by the appearance of the humans, saying their ugliness was not an exagerration. Seemingly agreeing to a joint mission to the surface of the planet to find out what was trapping them, Tarr instead directed Letek to attempt to capture the humans.
Encountering the two crews, the guardian was disgusted with the Ferengi, but he was impressed with the wisdom of Riker and the other Starfleet officers. After Riker convinced the guardian to release the Enterprise and Tarr's ship, the Ferengi were made to return the T-9 converter to Starfleet. Tarr complained but one last blast from Portal convinced him to stop complaining.
