Input: Article: The first action of the Franco-Prussian War took place on 4 August 1870. This battle saw the unsupported division of General Douay of I Corps, with some attached cavalry, which was posted to watch the border, attacked in overwhelming but uncoordinated fashion by the German 3rd Army. During the day, elements of a Bavarian and two Prussian corps became engaged and were aided by Prussian artillery, which blasted holes in the defenses of the town. Douay held a very strong position initially, thanks to the accurate long-range fire of the Chassepots but his force was too thinly stretched to hold it. Douay was killed in the late morning when a caisson of the divisional mitrailleuse battery exploded near him; the encirclement of the town by the Prussians threatened the French avenue of retreat.

If in the course of a lecture I stated an unsolved problem, the chances were he'd come to me at the end of the lecture with the complete solution scribbled on a slip of paper." Halmos recounts a story told by Nicholas Metropolis, concerning the speed of von Neumann's calculations, when somebody asked von Neumann to solve the famous fly puzzle:

Input: Article: Another unofficial but much more well-known mascot is Ronnie "Woo Woo" Wickers who is a longtime fan and local celebrity in the Chicago area. He is known to Wrigley Field visitors for his idiosyncratic cheers at baseball games, generally punctuated with an exclamatory "Woo!" (e.g., "Cubs, woo! Cubs, woo! Big-Z, woo! Zambrano, woo! Cubs, woo!") Longtime Cubs announcer Harry Caray dubbed Wickers "Leather Lungs" for his ability to shout for hours at a time. He is not employed by the team, although the club has on two separate occasions allowed him into the broadcast booth and allow him some degree of freedom once he purchases or is given a ticket by fans to get into the games. He is largely allowed to roam the park and interact with fans by Wrigley Field security.
