When you prank the Old Hag for so long that she finally decides to prank you back...

Missy running after her clothes that Miss Becky charmed to run from her.

We must remember that Missy is the younger daughter of Prof Mack and was raised in the corridors of the University where her mother worked. Being one of the oldest staff there, Miss Becky had been a prank recipient for years... Seems like she had enough.
