As "Mega" wrote, phone rang; no one there. Minute later, it rang again. Caller said he was from GE and that I had, some time ago, responded to questions re a smoke detector. [Not true.] Said I had won a $1200 security system. Asked what that had to do with a smoke detector, and he hung up.
I answerd the phone saying: South Side Pizza, pick up or delivery? This has worked for me in the passed. I have other choice words for these people, but found not to be as affective.
