Sorrow! Rage! Jon looks like he wants to punch that bitch... for not loving him! I'd really like to see Jon and Ellen go to the next level, too, because as far as I can tell, they've only spoken on the phone, and I can't wait to see her. She must like him though, because he's called every day this week... Hmm... Actually, maybe they are at the "next level," if not the final level to which all romances must aspire: it always ends with Ellen in silence, and Jon in despair or anger.
And God, it's great that Garfield chooses to insult Jon not for the topic of today's joke - which is Jon's failure at romance - but because in addition to being lonely, Jon looks like an idiot. Bonus cruelty at no extra cost. That's the Garfield promise.
