The previous journal kind of inspired this thread for me. What is your favorite school project you ever did that involved baseball? It could be in history, English, chemistry, what have you. Personally, mine was a persuasive argument speech I had to give in AP US History in my senior year of high school. Everyone used historically epic topics like abortion and whatnot. I, logically, as a baseball fan argued both for and against the designated hitter.
Got a chuckle out of my teacher. Hahah, I just remembered. Not only did I get a chuckle out of my teacher, he also ended up mentioning it in my recommendation letter to college as a "positive".
