Animals
Traveling in the car yesterday, I was eating a donut. There were some crumbs on my hands. I rubbed my hands together to get rid of the crumbs and this disgusted my wife.

HER: Ugh. We live like pigs.
ME: No we don't. It's not that bad.
HER: What's an animal that lives a little cleaner than pigs?
ME: Goats?
HER: Fine. We live like goats.

So it turns out we live like goats.
