The first laugh in that "<LAUGHS> Hey, Dr. Von Fusion" is a dedicated laugh section, which the model does extremely well, but it works because that's a natural place to laugh before actually speaking the following words. Skip ahead to "...robot chuckle. Jessica: <LAUGHS> I know right!" and you get an awkwardly time/toned light chuckle completely separated from the "I know" you'd naturally continue saying while making that chuckle. You can always rewrite the text to avoid times where one would naturally laugh through the next couple of following words but that's just attempting to avoid the problem and do a different kind of laugh instead.
