剧情简介：
Terri说自己怀孕了，拖着Will去看房，准备给未出生的宝宝一个良好的环境。然而什么都想要的Terri让Will倍感无奈，因为照他们的经济状况，压根儿就买不起这样的房子……

Will: Thank you. We can't afford this.
Terri: We already did the math, Will. All we have to do is give up Applebee's, and we won't run the AC for the first couple of summers.
Will: Well,we certainly can't afford the grand foyer, and the sun nook. I mean, if we bite off more than we can chew, we'll lose everything. You need to pick one.
Terri: Come with me. I'm going to show you something really special.
