My first thought was... BIN THEM.
But seeing that there are a few suggestions other than that, I thought that you could make puppets with them (like the ones we make with socks) and call them names like Mr and Mrs McThong who'd have quintuplets. Marks, Spencer, Five, Bikini and Briefs. You will have 3 left, so you could make the grandparents and the old spinster aunt, Auntie Beige Kilotte.
