One streaker was spared a painful injury by his own imaginative costume.

"I was wearing a cape and bicycle helmet to be different....I fell back on my head, the helmet saved my life, I fell really hard," Nick J. Britell '03 said. "I have some bruises, but it's not a big deal. I had so much fun it didn't really matter."

Towery said he felt his practical joke was successful. "I don't think its funny to see people get hurt, but the overall effect was funny," Towery said.

In addition to the water balloons and ice slick, this year's runners sported a variety of interesting costumes and paraphernalia, including capes, hats and bow-ties.

One masked man carried a sign saying "This is not shrinkage," in an allusion to the infamous Seinfeld episode concerning the effect of cold weather on male genitalia.

But not all of Monday night's activities were confined to the frigid night air, as a group of students from the Dudley House Co-op began things early in Lamont, stripping down to their undergarments about an hour and a half before others streaked in the yard.

The "Lingerie Study Break" is a long standing tradition in which several Co-op residents stand up from their books from time to time, remove an article of clothing, walk around the library, then sit back down and repeat the process until they are wearing nothing but their lingerie or boxers.
