I totally agree. Earl is fine and it would be okay to see this much of him if he was a recurring character, but I have very little interest in developing characters we don't see in more than one episode and who don't impact Jim or Blair's backstory.

"I'm all yours little buddy" is such a strange line (esp. to Jim) and so self-consciously said. Like he had already decided to say "I'm all yours" but then decided it was weird but then decided to say it anyway. As, ha ha, a joke! (But maybe I'm overestimating the extent to which people besides me plan out what they will say.)
