Andy Richter Controls the Universe (2002)

Season 2: Episode 10

While working on a manual for a deep frier, Byron proposes livening it up with a cartoon character. Andy tries to sarcastically shoot the idea down by suggesting a cartoon dog that tells people stupidly obvious facts, but when executives aren't thrilled with Andy's manual, Byron suggests the "Duh Dog" and the idea takes off. Meanwhile, Keith becomes addicted to fried food.
