Spats: Experiment 397 - S2-E14
Plot hole: The plot reveals once someone counts 1-10, the arguing effect wears off. However, when the boxing ring audience (all under the arguing spell) join in the counting after Lilo says "1...2...", the spell is broken for everyone in the crowd - but the audience only counts "3-10" (joining Lilo with the counting starting at "3") - this should not have broken the spell for them as they did not say every number.
