Ding Dong Installs A Doorbell

Mom: "I installed your new doorbell today but I only hooked up the ding, not the dong."

Me: "Har har."

Mom: "What? I'm serious. There were three wires but I could only find where to hook up two of them. So your doorbell goes ding but not dong. I guess that other wire was the dong. Can you live with just the ding?"

Me: "Was I adopted?"
