Expensive Barbie!
A man was driving home from work one evening when he suddenly realized that it was his daughter's birthday and he hadn't yet bought her a gift.
So, the man rushed off to the nearest toy store and asked the sales clerk, "How much is that Barbie in the window?"
The sales clerk replied in a condescending tone, "Which Barbie? We have Barbie Goes to the Gym for $19.95, Barbie Goes to the Ball for $19.95, Barbie Goes Shopping for $19.95, Barbie Goes to the Beach for $19.95, Barbie Goes Nightclubbing for $19.95, and Divorce Barbie for $265.00."
The overwhelmed man asked, "Why is the Divorced Barbie $265.00 and all the others are only $19.95?"

Speed limitIn 1865, a lower speed limit - of 2 mph in town and 4 mph in the country - was imposed in Britain under the Locomotives and Highways Act. The "Red Flag" Act also required three drivers for each vehicle - two on the vehicle and one to walk ahead carrying a red flag. It was repealed in 1896, after nearly two decades of strong support from horse interests. The repeal of the act was celebrated by a 60 mile car run from London to Brighton - at the new and previously illegal speed of 12 mph. That first run is now commemorated each year on the first Sunday in November at 7:30 am. Vehicles built before 1904 take part in the London to Brighton run. Bronze medals are awarded to drivers arriving in Brighton by 4:00 pm. |
