06x20 The Thing That Wouldn't Die (2)
As a result of the manner in which Dick settled his dispute with Liam, the group is ordered home. Of course, there are always loose ends to tie up before a long space trip. Dick wants Mary to accompany them, and Sally decides to instill confidence in Don. They organize a farewell party, and Harry and Tommy decide to charge everything and not worry about being around to pay the bill. They even hire Elvis Costello to sing "Fly Me to the Moon."
