An act first practiced at Brookfield Central High School in the mid-1990s. Several students from the Milwaukee suburb of Brookfield, being of a gentle disposition, sought a safer and more sanitary form of humiliation than the traditional swirlie, which involves holding someone's head in a toilet and then flushing. The new "Brookfield swirlie" consisted of holding the victim's head down on the surface of a water fountain (a water fountain of course being known as a "bubbler" to some but not all Wisconsinites) so that the fountain water shoots into the ear of the victim. In this era at Brookfield Central, a few girls practiced this more genteel "swirlie" (boys are far more likely than girls to practice the more dangerous traditional swirlie). Nevertheless, an undesired side-effect of the Brookfield swirlie was that the act was more public and in some ways riskier than the traditional toilet-based variety.
The Polar Plunge is an event for the benefit of the Special Olympics during which participants jump into a swimming hole in Lake Monona. Since the event takes place in late February (February 20th, 2010 at Olin Park), the lake is always frozen solid. Only the bravest (craziest) of souls dare jump. For many, sponsoring a "plunger" is the best way to participate in this very Wisconsinesque activity.
