I watched this episode again. "So Funny I Forgot to Laugh" is probably the worst episode of season 16 in my opinion. However, I was pleasantly surprised to see Tenzin Wangdu mentioned! (even if he did have a major redesign, going from a brown bear to a panda-looking bear)

Also still not impressed with all the dubbing in the flashbacks, but I somehow missed something the first time around: George's flashback included an entirely new sequence that wasn't originally in "Arthur's Dummy Disaster", where he had ducked behind a display of books, and Wally is now completely dismembered, carrying on like he's dying, and requesting one last drink of furniture polish before he goes.

I'm with you on this one. I didn't even notice the added flash animation with George's flashback. Guess it's time for me to go through season 1 on YouTube to refresh myself on the oldies lol.

So what required a redub, and what didn't with the flashbacks? That's what I want to know. Seems silly to mix old and new voices. I do think that George's current voice is actually quite similar to his original voice.

Did anyone ever notice how Flash Ratburn's fur is much more gray than previous seasons, and his clothes are less bright? His old coloring was way better.

I thought something was strange about Ratburn this season, but I couldn't quite pinpoint what it was. You nailed it though, and it IS much better the old way.
