As a Christmas present an elderly couple's daughter gave them a carbon monoxide detector for their home.

Some months later, the daughter's mother told her daughter that carbon monoxide was detected in their home.

Daughter: " How could that be? Didn't the carbon monoxide detector I gave you work?"

Mother: "No. We had to unplug it after a while. It kept beeping all the time!"
