Bad Habits

My four-year-old taught my one-year-old how to spit today. I was watching them and couldn't figure out quite what was going on until I walked over to the baby, who was in the high chair, and he spit in my face. Boys! I'm sure I have more of these days to look forward to! Anyone else have older kids who teach the younger ones bad habits?
