Perhaps this is not the forum to discuss contraception, but I think it is worth noting that the Sponge is coming back to the US market. I never used the sponge, but the fact that it was popular enough amongst women to inspire a Seinfeld episode, but was taken off of the market because the manufacturer didn't want to bother and update their production plant, really pisses me off. Women's contraception choices are pretty limited as it is, so taking a popular, easily accessible, and easy-to-use one off of the market because of, essentially, the company's stinginess...blows.
But in the interest of keeping this about TV let me just point out that the guy Elaine deems spongeworthy in that Seinfeld episode was played by Scott Patterson, who now plays Luke on Gilmore Girls. Spongeworthy indeed!
