Warning Label! Official Disclaimer! Beware!
This little book contains dangerous jokes. In the wrong hands, they could be harmful to health. During lab tests some caused such paroxysms of giggles that our guinea pigs needed medical attention. And if the jokes do that to guinea pigs, imagine their impact on humans.
There's also the possibility that these jokes will be good for you. In a world of woes and worries, riffling through these pages may offer a drug-free antidote to many emotional problems. But the publisher warns you that many of these jokes exceed 6.5 on the Richter scale of risibility.
