It's 10:30, Do You Know Where Your Children Are?

When I was a kid, every night at 10:30 the television station would broadcast this message, "It's 10:30, do you know where your children are?" Last night my son wasn't home at 10:30, so I called him on his cell phone, "It's 10:30, do you know where your parents are?" Him: "Probably in bed". Me: "It's getting late, are you heading home soon?". I think that's one of those sayings that gets lost on the next generation. lol
