A fly enters Eddy's voice box, and he cannot talk as a result. Ed and Double D give him a cowbell so he can communicate with them. Rolf acts as an interpreter, and Ed and Double D trust him despite him not actually understanding what Eddy is trying to communicate. Eddy's body language indicates that Rolf's interpretations are incorrect.
Eddy gets a zit, which Double D tells him is a natural part of growing up. Eddy is embarrassed about it and tries to hide from the other kids. Ed finds the zit funny and gets Johnny to come over and see it, to Eddy's dismay.
Eddy is normally treated with contempt by the other cul-de-sac kids. When he disguises as an alter-ego named Carl, all of the kids treat him kindly. Eddy is confused as to why they're being so nice, and Double D explains the concept of acceptance. He states that Carl has a clean slate, as he hasn't done anything to ruin his reputation, unlike Eddy.
