My sister had a practical joke to use on her daughter. When she was only a toddler, she kept saying in conversation that Jessica Simpson was OJ Simpson's daughter. Not all the time, just when it came up. We all thought it was hilarious, and it's pretty minor. The idea is that one day, her daughter will say it to someone else and get corrected.

Then the ease of fact checking that online made it impractical.

Then someone we never counted on - that daughter, being in high school, didn't know or care about either of those people. They don't come up in ANY conversations between high school kids. Or even us, at that point. One day, my sister brought it up and the kid goes "who?" And it dawned on her that it would never pay off. She told her and it was just an awkward silence followed by "um, ok?" Or something like that.

I guess the joke is on my sister for getting old?
