Son ask his Mum and then his Dad

Why wedding dresses are white....
Son asked his mother the following question:

'Mum, why are wedding dresses white?' The mother looks at her son and replies:

'Son, this shows your friends and relatives that your bride is pure.'

The son thanks his Mum and goes off to double-check this with his father.

'Dad why are wedding dresses white?'

The father looks at his son in surprise and says:

'Son, all household appliances come in white.
