San Francisco, CA -- San Franciscans will be racing towards a bicylcling event this Sunday -- in their underwear.

Locals David Caraway and Al Cummings are holding a cheeky event this Sunday in San Francisco called Critical Ass for bicyclists who want to ride their bikes in their underwear around town.

San Francisco is no stranger to Critical Mass. That's where hundreds of bicyclist at the end of each month ride in a mass, clogging city streets and stopping traffic during commute time as a way to show support for bike riders' rights.

But Caraway's Critical Ass is a playful parody of Critical Mass which he says is modeled after similar ones his friend in New York staged.

Caraway is hoping bad weather doesn't keep folks away. If it's cold he says he'll just wear his long-johns.
