Man on the Moon

I was driving my 3 kids home from a late afternoon movie this week when our attention was caught by a big beautiful full moon. Morgan asked if anyone could live on the moon and Sam took over from there. He said that a footprint would last for 2 years on the moon because there isn't wind like on earth. When Jack questioned how he knew this, Sam replied that a man named Armstrong took the first steps on the moon, and he was good at biking. As I was marveling at Sam's recall of these facts, and trying to imagine him choosing a biography from his school library, Jack finally broke the silence "Ah, that's not the same guy. Neil Armstrong landed on the moon. Lance Armstrong was the bike rider". Aha, pretty funny.
