That was my initial reaction too, before I heard the routine he did for the troops. Now, at best, I'll give him half credit. Based on his comedy bit, I question his motives.
Some people think he only did it to have bragging rights about it, I am not sure. Could be, but time wil tell.
As a former Marine, it was wonderful to have anyone visit us, it happened so infrequently, in fact, only twice that I remember in 4 years.
