All Grown Up! - Season 5 - Eps 7: Petition This!
Kimi leads a petition drive to ban cell phones in school. To prevent her from having the cell phones banned, Angelica hoodwinks Chuckie into helping her keep cell phones in school in her petition drive, while Susie helps Kimi counteract. Things get worse when during the debate at a school assembly, Chuckie reveals to the audience that Kimi wants a cell phone for Christmas, and they end up not speaking to each other and threatening not to attend their parents' (Kira and Chas) 10 year wedding anniversary. However, Angelica, Susie, and Tommy force them to attend to attend. At the Java Lava, Chuckie and Kimi argue with each other about cell phones until they make up after Tommy shows a video of their parents' wedding when they were babies.
