The video below shows former Massachusetts governor Mitt Romney (R) relaying a quip that former U.S. senator from Massachusetts Ted Kennedy (D) made at the 2006 signing ceremony for RomneyCare, a law that both men labored to make a reality.  Cato adjunct scholar David Hyman quotes Kennedy’s quip in this paper on RomneyCare:

When you come to a celebration of a signing and Mitt Romney and Ted Kennedy and the Heritage Foundation are all together, it’s clear one of us didn’t read the bill.

Romney paraphrases Kennedy’s quip at 1:12 into the video, to the amusement of the conservatives attending the National Review Institute’s Conservative Summit:

RomneyCare later served as the model for ObamaCare.  Guess who didn’t read the bill.
