After causing two incidents involving lying to Alberto, the Tibble twins fear they may end up in jail for lying. They swear to always tell the truth, but end up offending their friends and acquaintances. Alberto advises the twins not to say the first thing that comes to their minds and explains how they can be honest and nice at the same time. After Binky accidentally breaks Brain's new watch during a soccer game, the two get into several arguments while waiting for their parents (who are late) to pick them up.
