I believe it was Winston Churchill who said "Study History...STUDY HISTORY!! BLAHGHGA!!!" So to that end, I find it easier to remember important world events through helpful little snippets, cute and informative little bites of episodes in human history, in an easy to digest cartoon format. Here are a couple to keep in mind for your next mid term:
April 10th, 1912
"New York City, here I come!"
April 15th, 1865
"This play is just the thing to take my mind off those troubling nightmares of late."
