A man goes to the doctors complaining of migraines and headaches

After giving the man a regular check-up and running some tests, the doctor eventually returned with three bottles. One with blue pills, one with green pills, and one with red pills.

"This is a month's supply of pills." The doctor explains. "Every morning, take one of the blue pills with a large glass of water. Every lunchtime, take one of the green pills with another large glass of water. And at bedtime take one of the red pills with another large glass of water."

Concerned with the number of pills he's going to be taking, the man asks "What's wrong with me, doctor?"

"You're not drinking enough water."

Speed traps

In 1907, motor car speed traps were protested in a letter to The Times, London. Lord Montagu of Beaulieu (whose son founded the National Motor Museum) wrote to challenge anti-motorist complaints as opposing progress. To combat dust cloud nuisance from traffic, he called for more suitable roads: "reserved only for motorists and rubber-tired non-animal traffic - at least between large centres of population." About speed traps, he continued, "By all means let police-traps be placed where there is any reason to think danger may exist, but ... At present, the police neglect their other duties and look upon trapping as a regular sport" producing income to local government from the £5 or £10 fines for speeds of 20 or 30 mph.
