Every year, members of the Columbia University Marching Band invade Butler Library on the eve of the Organic Chemistry final to interrupt the last-minute studying done by panicking students.

The now-annualized event is known as Orgo Night, and each year the CUMB one-ups itself by topping the previous year’s antics with something even more absurd and over-the-top.

Naturally, this year was no different – except for the fact that a giant inflatable penis decided to stop by and enjoy the festivities.

This, of course, marks the third time in two weeks that genitalia have been used in a prank at Columbia.

The oversexed Columbians strike again.
