A Civil War anecdote that may provoke a chuckle or so:

There is a story purportedly about that photo of Lincoln and McClellan sitting in the tent looking at each other at Antietam. The photographer is supposed to have told them they would have to be very still for a long time, and Lincoln said, “That shouldn’t be too hard for George.”
