Gumball: Slackies, for when you gotta go, but you don't wanna leave.
The first lines Gumball and Darwin share when they first wake up:.
The cheeky expressions that Darwin and Julius give to each other at the end.
Darwin being aware of what Julius was doing the whole time, and trolling him just to teach him a lesson.
When Julius is telling his friends about Darwin's naivety, he gives the example that Darwin is holding the phone up.
Darwin got detention for adding "is bad" to it.
Julius got detention for TP-ing a tree so that it spelled "vandalism".
only to find out he'd accidentally ordered paper plates, which needless to say, don't smash very well. Eventually, Darwin runs out of plates to smash and has to excuse himself to go back to his room to order more plates online, then go to the front door to receive delivery and then bring the box back to the kitchen to resume smashing in anger.
When Gumball and Darwin confront Richard in the mistaken belief that he's having an affair with Samantha, Darwin keeps smashing plates as Richard keeps digging himself deeper due to Cannot Spit It Out.
