Apparently, my husband hums it while he juggles.
Now, my daughter comes up to me with items to juggle and starts 'singing' the song. At first I thought she was humming the circus song, Entry of the Gladiators. She goes 'Doo Doo Do Do Do Do Doo Do Do Do Do'. I was impressed. I was more impressed when I found out it was Led Zeppelin instead.
