Cut is the branch that might have grown full straight,
And burned is Apollo's laurel bough
That sometime grew within this learned man.
Faustus is gone. Regard his hellish fall,
Whose fiendful fortune may exhort the wise
Only to wonder at unlawful things,
Whose deepness doth entice such forward wits
To practice more than heavenly power permits.
Doctor Faustus, by Christopher Marlowe
Well, my rat never sold his soul to the devil (to my knowledge), but at least his demise wasn't as horrific as his namesake's.
To Doc! *raises a glass* We'll miss you, puppy.
