1. A term frequently used by politicians when accused of something scandalous. It means: "I did it, but as long as there's no smoking gun I will deny it completely." Most such scandals involve illicit sex, bribery, influence peddling or misuse of public funds.

2. A worn-out public relations phrase that nobody believes anymore. Nixon's famous remark -- "I am not a crook" -- sounds positively Shakespearian in comparison.
