Remember, remember, the fifth of November,
When Doc bumped his head and made it so tender;
He could not recall his singular sight:
Capacitors fluxing and time circuits alight.
Calvin the sailor with life jacket steady
Inquired, ‘Hey Doc, are you now ready
To freeze space-time in the tower-clock?
Banish the thought of paradox.
Not now, you see, but hither they come,
Your days on the continuum.

Composed on the occasion of November the 5th, not in honor of Guy Fawkes Day but for Doc Brown Day.
