The Simpsons/Barney Gumble

Single, an alcoholic (after being introduced to beer by Homer as a teenager), and living in a incredibly messy dump, Barney arguably remains Homer's best friend. His desperation for alcohol has been the source of many jokes. He remains friendly and good natured despite his unfortunate condition.

In Season ??, Barney finally kicked the alcoholism and transferred his addiction to espresso, which unfortunately led to the disappearance of his trademark belch.

Barney has demonstrated considerable talents as a singer, filmmaker, and snow plow driver, but keeps getting foiled by his various addictions.
