“This week is one of the most fun weeks of the year. There is always something going on outside of the Science Center and at night there are always initiation events you can witness,” says Alyson R. Gallotta ’06, who was also serenaded by the Delphic boys.

When done in taste, even performances during class time are getting laughs and cheers.

This Wednesday, for example, it was not the scintillating lecture or interesting subject matter, but rather the highly anticipated song and dance performances of both male and female final club initiates, that helped fill almost all 200 seats of lecture in the popular class Sociology 139, “The Study of Deviance.”

Word of a surprise appearance drew double the usual attendance.

The walls of Emerson Hall were filled with an unsynchronized but enthusiastic rendition of “It’s Raining Men,” performed by male final club initiates, as the classrom filled with students, a cow and someone dressed like Spiderman.

Assistant Professor of Sociology Mark J. Zimny said he was amused by the ruckus, joking that he “did not actually have a well prepared lecture in the can, thus he welcomed the unexpected intrusion with gusto.”

Zimny said he did not find the stunts disruptive, explaining that the students politely asked permission at the beginning of class and were respectful of the time constraints.

“In general I thought it was rather harmless and somewhat humorous. If it’s wholesome, and if it’s constructive it can be part of college, but if it crosses the line…I wouldn’t be supportive. I think just singing is fine, they weren’t doing anything explicitly salacious,” he said.

And the students milked Zimny’s good nature for all it was worth.

When he called on the student dressed as a cow later in the class, the boy-heifer approached Zimny’s podium and offered him his choice of vanilla or chocolate milk. Retaining his composure, an amused Zimny chose the vanilla milk, took a sip and continued on with lecture on deviance.

But not all of this week’s class performances have received such rave reviews.

With at least two disruptions during Wednesday’s Moral Reasoning 22, “Justice” lecture, many teaching fellows (TFs) and students left Sanders Theatre unamused.

Before lecture began, a handful of boys undressed down to their boxer briefs on stage, to the hollers and hoots of a Sanders Theatre audience.

But while students said they found this first incident pretty amusing, they said the disruptions that followed became increasingly less so. Halfway through the lecture, guys dressed as a cheerleader, football player and a referee ran into the class. The faux football player stormed the stage as the ref yelled ”Touchdown.” The trio then dashed out the door.

Later on, after boys yelled expletives from across opposite sides of the balcony and then fled, students responded with hissing.
