Years ago when I was about 10 years old, Granma asked me what I wanted for my Birthday so I asked her for a cheese souffle.  She made it in her oven and invited other people over.  When we were all seated at the table, someone opened the door and let the cold air flow in from the front door.  The change in temperature collapsed the souffle.  Grandma was holding the special spoon and looking at the collapsed souffle she had spent hours making. She had a Classic expression.  The idiot who opened the door got his ass handed back to him in front of the dinner guests -- guess who that was?  Grandpa Waldon (late getting back from Indianapolis at his job).
