On the other hand, it’s not like Nazi Germany. These people are voluntarily asking him to vacuum the fat out. They don’t necessarily want it back. In fact, they probably don’t...unless they’re planning to use it in their own diesels. Actually, this strikes me as one of the less unsanitary ways to get rid of the stuff. The only problem is, now I look at Michael Moore and I see a giant jerry can with glasses and a Tigers cap.
I’ll bet this guy drives a convertible with a top made out of stitched together skin from tummy tuck patients.
