In Urdu language there is a phrase that translates into English as two and a half hair which is said for someone with short thin hair.My mom used to tell me I had two and a half hair and I thought she meant literally.Once I asked my aunt how many hairs she had and she gave me a really confused look.I told ger since I had two and a half hairs she should know how many she had.My aunt burst out laughing.
Figured out the truth later on
