Funny story on the bus

We (staff) went to Masaya today to see the arts and crafts market there.  It's about a one hour bus ride from Granada.  Often vendors get on the buses for a few minutes and try to sell their products.  On our bus ride back, an extremely energetic man got on the bus and spoke (very loudly and quickly) about pills he was selling to help with "flatulence, and digestion, and the breakdown of fats in the pancreas, and flatulence, and bloating feelings after you eat, and flatulence..."  He also looked directly at us, and pointed when naming certain conditions.  Apparently I need to watch out for colon cancer.  I'm sure it was much funnier to watch than hear about.  He must have yelled the word "flatulencia" at least 15 times.  We were all bowing our heads down below the seats in front of us, trying to stifle our hysterical laughter.
