A Funny Thing Happened at Walmart.

Last Wednesday I went for my usual 20 mile  ride, but on the way home I decided to stop by their auto center to check on the cost of an oil change using Castrol motor oil.  So I proudly rode my trike up to one of their employees & asked "What brand of oil do you normally use when you do an oil change?"  She walked over to another worker & asked him a question, & proceeded to yet another employee & questioned him.  Then she turned & walked back to me, & with a quiet voice, said "WD-40!"

I must admit, we had a good laugh once I told her I meant, for my car!
