Heading into its fifth season, “Community” is a smart, exuberant comedy that is consistently ranked as one of the most inventive and original half-hours on television. This ensemble comedy centres on a tight-knit group of friends who all met at what is possibly the world’s worst educational institution – Greendale Community College. At the centre of the group is Jeff Winger (Joel McHale, “The Soup”), a fast-talking lawyer who was caught with a phony college degree. Disbarred until he could earn a legitimate degree, Winger chose Greendale, thinking he could breeze through the mediocre school without a hitch. However, he soon found himself the reluctant leader of a disparate group of misfits, all stuck at Greendale for different reasons.
