The Lemon Fool

My wife found out yesterday that she was adopted. She was devastated and kept asking "why didn't they want me?"
I took her in my arms and comforted her. After a while, still in tears, she kissed me and asked me to make love to her.
With hindsight, shouting "WHO'S YER DADDY?!" halfway through probably wasn't the best idea.

Son: "Am I adopted?"

Dad: "Not yet, we still haven't found anyone who wants you!"

Dad: "Son, you're adopted!"

Son: "I knew you weren't my real dad!"

Dad: "Of course I am. Now pack your bags; you're new parents will be here in 30 minutes to collect you!"
