Doonesbury by Garry Trudeau for April 02, 1973
Reporter: Mr. President, in view of the new peace in Vietnam, we were wondering if we could finally have a look at your secret peace plan. Nixon: Mr. Rather, I can think of no reason why not! Now that peace is no longer a secret, I am going to take that secret plan out of my pocket and read it to you. Hmmm... I can't seem to find it... here! No, that's my laundry slip... hmm... it must be in my other pants... anyway, the important thing is that it worked! Right? Right?
