The Dream (ballet) Puns

So, I have this pair of shoes. They started off as wedge heels. One day, I noticed that the heels were coming off, so I took them off. I can still wear the shoes as ballet flats. Anyway, today my dad walks in and picks up one of the heels. "Look at the poor little lost sole," he said. I responded with a Dream Theater joke that was also very 'dad': "Just send it to the Ministry of Lost Soles!" Then, he picked up both of them. At the exact same time, we said, "Sole mates!"
