Okay, Cie's story reminded me of this, for which I think I should sue my parents.
My dad is quite the handyman, and back in the '80s he decided to put ceiling fans in all the bedrooms.
Their room went great. My brother's room went great. My sister's room went great.
My room didn't appear to have a hole drilled in the ceiling to receive the fan.
After measuring again and again, and climbing into and out of our very hot and unfloored attic, Dad discovered that he'd measured wrong originally, and drilled the hole for the ceiling fan in my closet.
After we got that straightened out, Dad hung my ceiling fan with no more untoward occurrence.
Thing worked like a charm for several years, until one morning I got up for school, stood under the fan, pulled the light cord . . . and the ENTIRE THING, fan and huge light fixture and all, came down and hit me squah on the top of my head.
OUCHHHHHH!!!! Were you seriously injured?
