I would have bet good money that was a fake Shakespeare quote, or maybe as they (you know who) say today "alternative Shakespeare". But no, apparently it is for real from "The Merry Wives of Windsor, Act 2 Scene 2":

Eleven o'clock the hour.
I will prevent this, detect my wife, be revenged on
Falstaff, and laugh at Page. I will about it;
better three hours too soon than a minute too late.
Fie, fie, fie! cuckold! cuckold! cuckold!
