After visiting my Great Aunt...
After visiting my Great Aunt Annie, I travelled home in her old jalopy. The car was old and battered, it had a leak from the petrol tank, and I was stuck in second gear. This meant that I could only travel along at a steady 30 miles per hour and managed a paltry 20 miles per gallon of fuel. At the start of the journey I had placed exactly 10 gallons of fuel into the tank. I knew though, that the fuel tank lost fuel at the rate of half a gallon per hour. Just as I arrived home, the car stopped because it had run out of fuel and I had only just made it. How far was it from my Great Aunt's to my home?Correct answers: 29

Wet Smokers
Two old ladies were outside their nursing home having a smoke, when it started to rain. One of the ladies pulled out a condom, cut off the end, put it over her cigarette, and continued smoking.
Lady 1: What's that?
Lady 2: A condom.
Lady 1: Where'd you get it?
Lady 2: You can get them at any drugstore.
The next day, the first lady hobbled into the local drugstore and announced to the pharmacist that she wanted to buy a package of condoms.
The guy looked at her kind of strangely (she was, after all, in her 80s), but politely asked what brand she preferred.
"Doesn't matter," she replied, "as long as it fits a Camel."
