Haha, that reminds me of a picture we had in my office back when I was a loan officer full time.  My company only loaned on double wides, and not single wides.  Well, there was this pic that said: "Remember, when processing a loan, to know the difference betwen a double wide, and a double high"  Then there was a picture of a single wide stacked on top of another single wide, and it had a two story deck and everything.  I wish I had that picuter, it was hilarious.
