The credits start with a memorial card that reads, "In Memoriam: Denis Akiyama May 28, 1952 - June 28, 2018". Denis Akiyama played Koji, Dot's husband in the beginning of the series, but the character tragically dies of a heart attack, ostensibly written off because Denis Akiyama himself passed away.
Dot says Harley ate pancakes as a kid and that's what made him fat. Jerry O'Connell famously played the chubby kid in the movie Stand By Me
Speaking of the new chief, Harley says, "you get more bees with honey", but bees are not attracted to honey, they make it. The correct expression is actually, "you get more flies with honey, than with vinegar", which actually makes sense since honey is sweet and vinegar is acidic and sour/bitter.
