Professor McGonagall was running through the halls in her tartan night robe at full speed.
"Albus! Albus!" she called as she rushed towards his office. She knew he was still working out new administrative details for the upcoming school year.
"Albus!" she called one last time as she neared the base of the stairs to his office nearly out of breath.
The door at the top of the stairs was wrenched open and Albus poked his head through. "Great Merlin, Minerva! What's going on?" he asked.
"I've had an epiphany!" she said. "I can't believe I've never thought of it before."
"Well what is it, woman?"
"All we have to do is fire Binns!"
Albus blinked. "Now how come I never thought of that?"
