...which is 1994:

Lots of teen magazines showed only the popularities of Mark, Mario, Tiffani, Elizabeth and Lark. But on one teen magazine, including Dustin and Dennis, you didn't noticed that Dustin wanted to quit playing a nerd because that nerd role made him suffer from both several mental disorder diagnoses and popularity losses. Few weeks later, both Peter Engel and the critics did understand Dustin's double suffering, but his nerd role wasn't the cause because of the way he played well. It turns out both of his double sufferings were badly caused by both Dustin and his nerd role being carelessly both included and mishandled in the original series in a wrong technique. But this entire Dustin's reasonable double mental suffering could not be multi-publicized because it cause the too many numbers of career letdown on both original castmember and crewmember groups, but more on Dustin's.

That's the reason why Peter Engel had no choice to make this decision to adopt both Dustin and his nerd role into the New Class sitcom. Although, this new class sitcom should not have its setting in both Bayside and Valley High School type of areas officially in order not to be completely trashy, TBH.
