Wow. As Twitchy reported, a man started playing “Amazing Grace” on the bagpipes outside the evacuated Boston courthouse, where a large crowd of media and spectators had gathered.

It was an incredibly touching and moving display.

But, to Boston Globe reporter (and self-proclaimed star professor at Harvard night school) Billy Baker, it was a mystery and totally inexplicable.

Twitter is at the ready to help the “real journalist” out by providing a Teachable Moment.

Ace of Spades schools the idjit reporter as only he can.

His fellow Twitter users continue the lessons.

Besides being a “star professor,” he also claims to be a Southie guy.

And some homework for the Harvard-man.

Amen.

Update: He deleted his tweet. Sorry, “professor”: Twitchy is forever.
