Stereo Fibbing

Two characters are conspiring to deceive a third, but they haven't worked out their story in advance. When questioned, they blurt out answers in unison, which naturally are different answers, requiring further lies to explain how both blurted answers can be true.

For added comedy, the characters may then swap answers, each one trying to change his own answer to match his co-conspirator's, or their excuses may start blending together.
