What is Bullshit Baffles Brains?
1.
A deception. To put on such a good show the inspector is so impressed (s)he won't bother with a detailed check or to question anything.
Private: I can't believe the general was so impressed with that dog and pony show sir. It's a good thing he didn't really inspect the base, it's SNAFU!
Sargent: Bullshit baffles brains private.
