My dad is a funny man - embarassingly so for his children. Public places failed to reign in his moodiness and he refused to be servant to society's proprieties. Unfortunately. Then again sometimes things just slipped out, so to speak.
One little anecdote: My dad and oldest brother were at Quality Dairy to buy some doughnuts. The lady at the counter asked my dad what he wanted and my dad bent over to get a good look. As he bent over, he farted loudly. My brother quickly, though non-chalantly, wandered to the back of the store. My dad, however, simply looked up at the lady at the counter and said, "I don't want one of those."
