here’s a story of some ladies in their 80’s who were on the highway and were stopped by a policeman for going 40 mph on the highway.  When the officer asked the driver why she was going so slow, she said she was going the speed limit.  The wise officer figured it out and said, “Ma’am, 40 is not the speed limit.  It’s the highway number!”  Then, after looking at the passengers he asked, “Ma’am, why do your passengers look so terrified?” The driver responded, “because we just got off of highway 95!”
