Season 7, Episode 9: "The Sponge"

But I am birth-control shopping today.

-Are you still on the pill? -Oh, Kramer--

No, I think birth control should be discussed in an open forum.

-The Sponge, okay? -Sponge?

The Today Sponge.

But wasn't that taken off the market?

Off the market? The Sponge? No, no. No way.

-Everybody loves the Sponge. -I read it in Wall Street Week.
