Leonard Flyyn-Boyle (also known as Lenny) is a character from the Nickelodeon show, Fanboy and Chum Chum.
Lenny is the manager of the Frosty Mart store, where he and Boog work. Unlike Boog, Lenny is slightly more focused on his job, although he is usually seen standing with an unsatisfied look or napping behind the cashier counter. Lenny dislikes Fanboy and Chum Chum, finding them traumatic, irritating, and stressful. Lenny has made some plans to get rid of them, though always failing. In all fairness however, there antics, and constant bothering of him, do drive him next to insane, in one story it was shown before he met them he was happy, hard working and joval.
Lenny's character is very similar to that of Squidward Tentacles. Both seem to be dissatisfied with their lives, hate the main protagonsists of their shows, and are very accident prone. This characteristic is shared with other characters such as Rancid Rabbit from CatDog and Benson from Regular Show.
