Dear Diary: Valerie Jarrett wanted to do me a favor while I was in rainy Charlotte, N.C. today. She arranged for some guy from Florida to over-fly the South Lawn in a gyrocopter and drop a choom bomb that she could collect at leisure and hand over to me as a nice surprise. Alas, the pilot lacked fine control, dropped the choom okay, but then provoked widespread alarm by crash-landing in the vicinity of Congress. Oops.
