Zappa and Kaufman
On 11 September 1977, after Zappa's road manager Ron Nehoda committed suicide, Kaufman was quickly brought in as his successor. He remained their road manager until April 1978. He can be seen in the film Baby Snakes mimicking a trombone just by making vocal sounds. Zappa based the song Why Does It Hurt When I Pee? on an incident when Kaufman actually asked this question after leaving the toilet.  
In 1993 Kaufman published his autobiography Road Manager Deluxe, for which Zappa wrote a little acknowledgement.
