Go wash clothes

Because they had a 5-year-old son, a young couple decided to communicate cryptically with each other when feeling romantic:

'Let's go wash clothes' would mean 'Let's go make love now!'

One late afternoon, the father called the son. "Son," he said with urgency, "go tell your mom I want to wash clothes."

The son ran to the kitchen where the mom was preparing dinner. "Mom," he said with full innocence, "dad said to tell you he wants to wash clothes..."

The mom was busy. "Go tell your dad," she commanded the son, "cannot wash clothes now. The washing machine is broken."

AFTER DINNER, the mom called the son. "Son," she whispered softly, "go tell your dad to come wash clothes now..."

The son ran to the dad. "Dad," he said, "mom said to go wash clothes now."

"Now she tells me!" the dad said. "Go tell your mom I've already washed the clothes by hand!"
