I have started meeting with a friend and a bunch of his friends at a restaurant on the first Thursday of the month....to talk bikes and guy stuff. Last week the discussion was about the smell of Castor oil, and how the guy used it in his weedwacker just to make it more fun.
I just ordered one of those candles for the next meeting!
