"I haven't got a car or a house. I've got a wife, but I didn't pay for her! I spend all my money on my glorious wife. She's here with a knife at my throat!"

This quote by Mackenzie Crook is a funny means of expressing his love for his wife. He is stating that he has not invested in product belongings such as a car or a house, yet rather has actually spent all his cash in his wife. He is also indicating that his wife is so important to him that she is worth more than any kind of material possession. The joke is that he didn't have to spend for her, yet he still spends all his cash on her. The joke is more highlighted by the fact that his spouse is present with a blade at his throat, implying that she is willing to do whatever it requires to see to it he remains to invest in her. This quote is a funny method of expressing the significance of purchasing relationships as opposed to material properties.
