### I can not tell a lie...

A married man and his secretary were having a torrid affair. One afternoon they couldn't contain their passion, so they rushed over to her place where they spent the afternoon making passionate love. When they were finished, they fell asleep, not waking until 8 o'clock that night.

They got dressed quickly. Then the man asked his secretary to take his shoes outside and rub them on the lawn. Bewildered, she did as he asked, thinking him pretty weird.

The man finally got home and his wife met him at the door. Upset, she asked where he'd been. The man replied, "I can not tell a lie. My secretary and I are having an affair. Today we left work early, went to her place, spent the afternoon making love, and then fell asleep. That's why I'm late."

The wife looked at him, took notice of his shoes, and yelled, "I can see those are grass stains on your shoes. YOU LIAR! You've been playing golf again, haven't you?"

### Paul R. Ehrlich

Born 29 May 1932. Paul Ralph Ehrlich was an American biologist and educator who in 1990 shared Sweden's Crafoord Prize (established in 1980 and awarded by the Royal Swedish Academy of Sciences, to support those areas of science not covered by the Nobel Prizes) with biologist E.O. Wilson. He has been a pioneer in alerting the public to the problems of overpopulation and in raising issues of population, resources, and the environment as matters of public policy. Ehrlich is regarded as the co-founder, along with Peter H. Raven, of the field of coevolution, and has pursued long-term studies of the structure, dynamics and genetics of natural butterfly populations.
