This episode takes place sometime after Easter, since Mr. Simmons mentions that Eugene got injured on Easter.
We learn that Dino is 67 years old. This is reaffirmed in "Dino Checks Out".
In the episode, Dino is 67 years old. However, in The Old Building, it is implied that he is around Grandma and Grandpa's age.
Dino has performed at thousands of concerts.
The credits send out a special thanks to "Ol' Blue Eyes," a reference to Frank Sinatra.
There is a box of rat poison in the janitor's closet, which serves as Dino's dressing room.
At the end of the episode, Gerald is seen dancing with Phoebe and Arnold is seen dancing with Rhonda.
When Arnold announces to his classmates that Dino will be performing at P.S. 118, Stinky says "That old fat guy? I thought he was dead." Grandpa says the exact same line in "The Baseball" regarding Mickey Kaline.
Arnold says, "It's not over till it's over," a quote often attributed to Yogi Berra.
In the previous year, Dino made a record about hip-hop.
