Those roguish pranksters from Princeton’s marching band have done it again.

The band stopped by the Butler Library lobby just a few moments ago to blast Columbia midterm studiers with a drumline routine and plenty of brass honking. Although it’s possible the Princetonians were simply lost, Bwog chalks up the visit to pre-homecoming game merrymaking.

They have since departed and appear to be touring the campus, at one point serenading hungover freshmen in Carman.

Now, we would admit that Princeton got us this time, but when your prank requires that you wear orange plaid and porkpie hats, Bwog has to wonder exactly whom the joke is on.
