After a failed mac-n-cheese recipe, Milo, Melissa and Zack decide to order pizza. As they wait, they share some of their most hidden secrets, but Zack refuses to tell his, and in fact gets extremely nervous about some peculiar things.
Milo's attempt to cook macaroni and cheese for Zack and Melissa ends with a mac and cheese explosion that ruins their clothes. After changing into spare sets of Milo's wardrobe, Zack reacts nervously when Melissa says that the three look like part of a boy band.
Melissa, Milo, and Zack decide to order pizza and to their surprise, the online "pizza squire", Veronica, knows Milo and appears to recognize Zack. The three are inspired to share secrets: Milo confesses that his backpack "isn't his", Melissa reveals that her two front teeth are false, and Zack manages to avoid the subject.
Meanwhile, Veronica is making her way towards Milo's house avoiding many hazards. She eventually arrives safely at the house and is revealed to be the previous owner of Milo's backpack and his former babysitter, who used the backpack and various methods to deal with Murphy's Law. Before she leaves, she blows a kiss to Zack after saying, "I was a huge Lumberzacks fan. Chop, Chop, Chop". To Zack's chagrin, his friends soon search online and discover that Zack was once the leader of a boy band, The Lumberzacks, of which he is now embarrassed. Melissa, Milo and Zack entertain the idea of starting a band of their own with Melissa on bass and Milo on accordion.

(The truck driver glances where Diogee is looking and sees the fire in his way.) Truck Driver: Wow! Timber! (He swerves, and all the dirt in the back of the truck spills out and smothers the fire.) (Diogee barks and jumps off the truck into Veronica's arms.)
Veronica: Diogee. You're a lot bigger than I remember. (She puts Diogee on the sidecar.) Here you go. Let's take you home.
(Milo and Melissa are listening to "Chop Away at My Heart", to Zack's chagrin.) Zack:Please turn it off. I will give you this dollar I found in your pocket.
Milo, Melissa, and Zack mention that they should form a band in this episode, with Melissa on bass and Milo playing the accordion. This actually happens in "School Dance", to substitute the original band, and officially in "Battle of the Bands". Additionally, The Lumberzacks re-appear.
When Veronica leaves after delivering the pizza, she rides away on an ostrich. Knights riding ostriches was the central theme of the 1982 video game,Joust, and its 1986 sequel, Joust 2: Survival of the Fittest.
Towards the end of the episode, Milo mentions that he has an accordion, an allusion to his voice actor, "Weird Al" Yankovic, being an accordion player.
After Veronica launches her soda powered sidecar, she stabs the door with her unsheathed broadsword to use as a tiller, however, in subsequent scenes the sword, still serving as a tiller, is in it's scabbard.
During the flashback images that show Veronica babysitting younger Milo, one image shows the top half of her body with a lighter skin tone than the bottom half of her body.
When the Lumberzacks are at the water slide in the music video, there is no log behind Zack. But in the close-up of Zack, a log appears out of nowhere.
