This story goes back nearly 40 years - when Jimmy Carter was running for President of the US. (as an aside, in my opinion he was probably one of the most honest modern presidents we've had but also one of the most ineffective). Jimmy had done a "Playboy" interview which was widely discussed.
"Playboy" magazine actually had good cultural content and for a time the "Playboy Interview" enjoyed a remarkably strong reputation.
Anyhow, in 1976 I was at a lunch table with a bunch of lawyers, judges, business folks, etc. and Jimmy's interview was the animated topic. In it Jimmy admitted to having "Lusted in his heart" a few times. Just as we were discussing the "Lust" line, a blonde bombshell walked past our table - red dress (short, of course), cleavage, heels, etc. and the talk died down while male eyes watched the spectacle.
After a few moments of silence, one of the group drawled, "Speaking of Lust: put me down for two regular and one un-natural".
