In this video, you can see Jessica Hecht (who plays Gretchen Schwartz on Breaking Bad, Susan Bunch on Friends) and Tamayo Otsuki fully naked. They show their boobs, bush and butt. In this video, you can see them soing aerobics naked on a live tv show.
If only Moon Unit Zappa (Katie in the control room) had got naked as well, that would have been so cool.
