Honk is the ninth episode in Season 1 of Clarence.
Clarence tries to improve his communication skills through a squeeze horn.
The episode starts with Nathan and Dustin playing with Taffy Cards in the hallway, until Clarence comes in with a fake card, saying he won. In class, Belson was telling his opinions about the story he read. After him, Clarence talked about how if the jail was made out of cake, then he can eat his way out.
Ms. Baker was "intriuged" by this. Clarence, Jeff, and Sumo then talked about what happened in class. Sumo liked his idea and added on to it. But Jeff tells Clarence that his sense of humor is not right and that he should act more like others. Taking Jeff's advice, he goes home after school, watching TV so he should get an idea of how to act.
At first, he acts likes a TV host, but then sees several films starring the Marx Brothers with one of them (Harpo) playing with a horn. He loved this and bought a horn for himself so he could do the exact same thing. In school on the next day, he played with his horn in various antics, First, when he and his class was pleding adligeince to the flag, he squeezed his horn randomly. Then the announcer said about the water park competion that was happening tomorrow. After that, there were more announcements that were boring and Clarence squeezed his horn too make it fun. Later on he went around school squeezing horn in various places. Jeff tries to talk Clarence out of his habit but failed. At night in bed, Clarence was sleeping at playing his horn at the same time. Chad slept through it but Mary didn't.
The next day, when the winner was about to be announced on who was going to the water park, Clarecnce squeezed his horn and nobody in the room knew who was the winner except for other classes. Later on, Breehn was doing very important chemistry when Clarence squeezed his horn and ruined everything by making Breehn squirting the chemicals at a beaker that has liquid, causing it to mix quickly then leaking out of the beaker and onto the floor and causing the fire-alarm to beep. Clarence was upset with what he had done and people were too. At Jeff's house, Jeff, Sumo, Kimby, Courtlin, Malessica, Belson and Percy form a circle to help Clarence with his addiction. They talked and Clarence went home thinking they accepted him being honking all the time, leaving Jeff upset.
Clarence was in bed later that night and was talking to his horn. Crying, he decided to flush his horn down the toilet and flushed a rose so the horn will know that he still loved him. However, he saved horn with the help of Chad. Mary was miserable of this because she couldn't sleep and some toilet water got on her. In the morning, Clarence hid his horn in his backpack so know one will know he has it. However,
he was soon ambushed by students with horns with Jeff and Sumo watching him by a far.
The students tried to attack him including Breehn and Percy (Jeff and Sumo did this so Clarence can stop), but Clarence got an idea. He played his horn and all the kids made music causing Sumo to laugh and leaving Jeff confused. In the end, all the kids joined in a big musical number, with Jeff playing along as well. Unfortunately, all the horns were taking by the teachers in the end. Jeff learned that being true to yourself is the only way to make good friendships and Clarence learned that when you lose the horn, you get the whistle, which he did. However, it was taken away from him by Ms. Baker.
