While I'd hate to defend that horrible episode, how come no one else picked up on how out of character he was in that episode where everyone kept giving George the business? He was actually worse in that episode than the other one. In fact, that entire episode was a far better anti-bullying episode all over, and a turning point for the character of Francine. George's heartbreaking line of "it's not safe here," punctuated with paranoid looking around speaks better volumes than a crybaby Sue Ellen who was also out of character.At this point in time, I'm with you, I'd kind of like to see some more episodes where, oh, I don't know... Arthur is the focus. Arthur's barely even been a minor focus of the season so far, and we've had more episodes where he's completely absent. I get that the show's been on for so long and there's so many other different characters that they can explore, and they have, but it's still Arthur's show after all, and it'd be nice to see an episode where's the focus... and not forcefully out of character like in "So Funny I Forgot to Laugh."
But yeah, Arthur's lack of appearances really seems like it stems from the "Arthur is the every kid, and that's boring" bit. On the one hand, I'll admit some of the other kids are more interesting. I like Buster and Binky much more anyway. But on the other hand, he's a flawed character with personal problems of his own. His existence is rife with drama and comedy potential, even without D.W. bratting it up all over. Sure, they can't inflict him with asthma, dyslexia, or developmental issues that kept him back a year, but it's not that long ago when things were happening to Arthur that the other kids were involved in.

If you just ignored him, they would have disappeared from reality TV. Of course, Duck Dynasty merchandise over here sells like a lead brick filled with sugar free gummi bears, so, at least it's something.
