My son's 6th grade teacher was presenting the class with hard problems
yesterday and said 'okay, ready for this next one, it's a doozy' and the
class responded 'um... what's a doozy?'
surprised the teacher responded 'oh, I guess that must be old lady talk.'
my son replied, "I know what doozy means, does that make me an old lady?"
The entire class erupted in laughter.
