An Emmy-winning show about two best friends who try to turn their boring jobs into exciting adventures is ending its long run on Cartoon Network. Deadline.com reports that the cable net will pull the plug on the animated “Regular Show” after its eighth season, which premieres Sept. 26.

The series is created and executive produced by JG Quintel, who also voices park groundskeeper Mordecai, a 6-foot-tall bluejay. Mordecai’s pal Rigby, a hyperactive raccoon, is voiced by William Salyers.

“Season eight will present the ultimate intergalactic battle of good versus evil as Mordecai and Rigby are joined by Pops, Benson, Muscle Man (all voiced by Sam Marin) and Skips (Mark Hamill),” Deadline notes.

The show, which began as a student project by Quintel when he was at CalArts, was the first series to be greenlighted as part of Cartoon Network Studio’s Artists Program, back in 2008. The series won an Emmy for Outstanding Short-Format Animated Program in 2012 for “Eggscellent.”
