Different Interpretations

I almost forgot about this conversation which occured during dinner after the minor car accident last Friday night.

Spinxie to Mum & Aunty: I banged into someone's car just now. ... (and the rest of it)

Aunty: I think you saw a 'leng chai'

Mum: No, no, no, I disagree. Someone saw a 'leng lui'

Everyone laughed uncontrollably.
