From QED: The Strange Theory of Light and Matter, by Richard Feynman
"When calculating terms with couplings, we must consider (as always) all the possible points where couplings can occur, right down to cases where the two coupling points are on top of each other -- with zero distance betweens them."
From Chapter 4, Loose Ends
