Domestic Appliances

Inspired this joke:

A fresh-faced lad on the eve of his wedding night goes to his mother with the following question. "Mom, why are wedding dresses white?". The mother looks at her son and replies, "This shows the town your bride is pure." Thoughtful, the lad goes to his father and asks. "Dad, why are wedding dresses white?" The father looks at the son in surprise -- "All domestic appliances are white!"

For a challenge elsewhere. Uploaded today as it's very unlikely I'll ever do something like this again :)
