Ladies and Gentlemen, meet Typhoid Tillie. Tillie raised a ruckus this morning at 7th and Montana when -- as she paid for her cappuccino -- she warned Barista Kenisha, "Be careful, research shows that the average dollar bill has 1,014 germs on it." "I'm sorry," I chimed-in, "What did you say?" "Oh," she chirped, "I just heard on the radio that the average dollar bill is infested with germs." With that, she accepted her change from Kenisha and made an accidental grab for my coffee cup. Realizing her mistake, she passed me my cup. I looked at the cup, then at her hand -- which was still clutching several dollar bills -- and couldn't help wondering if there was a hidden camera somewhere shooting a Purell commercial. As Tillie walked out the door, I couldn't resist calling out to her: "Be careful with that door handle ... research shows you might as well soak your hand in a Petri Dish ...!"
