"To be or not to be? That is the question."
"Friends, Romans, countrymen: lend me your ears."
"Double, double, toil and trouble ..."
"For he today who sheds his blood with me shall be my brother"
"Neither a borrower nor a lender be ..."
Etc..
Not that BS's quote is anything but BS ... Neither Shakespeare nor Caesar ever said those words.
Heaven knows I’m no expert, but I think those quotes are part of longer passages which are Iambic pentameter.
Reading Shakespeare I have noted that he will begin a line with one character speaking and have the line finished by another character in order to keep the form intact.
In any event, as you point out, Babs should have known better.
