sponsoring Kramer for an AIDS Walk, Jerry spots the name of an
old college classmate on the sign-up sheet. Over Elaine's
objections, he copies down Lena Small's phone number and calls

George to tell Susan everything, including Jerry's secret.
Meanwhile, when her favorite birth control device, the Today

until she finds the last remaining case.  When Susan sends him
to pick up some birth control so they can make up after their
fight, George discovers she uses the sponge, too. Knowing Elaine
has the last remaining case, he heads for her apartment. But
after refusing George's request to borrow one, Elaine also has
second thoughts about sex with her boyfriend Billy for fear of
