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 Jonny to come over and see it, to Eddy's dismay.
