I'm Going to Put It in Because.

Zod's wife doesn't want the gurgler, but he wants to have one in back. He calls her and asks if she would agree to a raffle where it is very unlikely that you will win. She says 'yes' so they try again - this time with more tickets. The winner gets an Incincarator for their kitchen which Zod has never used. But Hamish can still install his girlfriend's car as part of the prize.
