Furniture Disease

Matt went into Doc Steven's office for his annual checkup, and the Doc asked
if there was anything unusual he should know about. That left it pretty wide
open, so he told the Doc that he found it real strange how his suit must have
shrunk just sitting in his closet, because it didn't fit when he went to get
ready for a wedding recently.
The Doc said, "Suits don't shrink just sittin' there. You probably just put on
a few pounds, Matt."
"That's just it, Doc, I know I haven't gained a single pound since the last
time I wore it."
"Well, then," said Doc, "You must have a case of Furniture Disease."
"What in the world is Furniture Disease?"
"Furniture Disease is when you reach that stage in life when your chest starts
sliding down into your drawers."
