The involvement of Frost in "TW3" led to an intensification of the rivalry with Peter Cook who accused him of stealing material and dubbed Frost "the bubonic plagiarist". The new satirical magazine "Private Eye" also mocked him at this time. Frost visited the U.S. during the break between the two series of "TW3" in the summer of 1963 and stayed with the producer of the New York City production of "Beyond The Fringe". Frost was unable to swim, but still jumped into the pool, and nearly drowned until he was saved by Peter Cook. At the memorial service for Cook in 1995, Alan Bennett recalled that rescuing Frost was the one regret Cook frequently expressed.
