What famous mid 19th century historical figure’s pants fell down while engaged in a duel?
Answer: Alexandre Dumas, the French novelist and playwright. Dueling in an abandoned quarry as a young man, his trousers fell down right before the contest, much to the amusement of those present. Luckily for Dumas it did not affect his concentration or aplomb, as he won the duel.
