Father Jebidiah-may-I?

One evening, since im catholic, i went to confession for a good hearty laugh (and my parents made me go!). As I was talking the priest or father "jebidiah-may-I" he said that saying jesus mary and that other guy is paying disrespect to christ and not reverence! So okay that was a sin. I felt horrible and sinfully dirty ! Well before I went in the screen with the priest, some woman tried to cut in front of me in the line, so I ran in front of her and everyone gave me a dirty look! The priest said that was a sin as well. So out of curiosity, since everything I did was sin I asked the priest a question that had him stumped! "father, if i were to go onto the top of the empire state building and were to drop a penny, would that be a sin?" well he thought about it and told me to grow up! He indirectly stated that I was sinning for asking that question and I was mocking the church! Can I never win? So knowing that a penny were to accelerate in speed and force drastically when you throw it while at the top of the empire state building, would that be a sin?
