The Love Tester is a coin operated machine that sits next to the bar in Moe's Tavern. It can be seen being used by many characters including Aerosmith's Steven Tyler. Apparently, the story behind it is that Moe had the money for either cable for the bar or the machine and obviously he chose the machine.
During the time that The Planet Express crew were transported into The Simpsons comic, Bender was given free beer at Moe's Tavern due to the impression he was a mascot Duff Beer. He was later kicked out when Moe caught him getting intimate with the Lover Tester. Bender claimed that the "little flirt started it".
