我们星期八离婚我们十三月结婚
[wŏ men xīng qī bā lí hūn wŏ men shí sān yuè jié hūn]
We divorce on Tuesday the 8th (there's no day 8 in a week) and we get married in the 13th month (no calendar follows such a system). It describes two impossible events that satirize contradictions or impossibility in real-world conditions, maybe pointing out unrealistic relationships between events, often using absurdity for humor or to express helplessness over bizarre situations.
