1. Anna Gunn
Known for: "Breaking Bad"
Seinfeld Appearance: "The Glasses" Her "Breaking Bad" husband Bryan Cranston had a "Seinfeld" role that everyone knows about, but not many know Anna Gunn had one too. She played one of Jerry's many girlfriends in a 1993 episode. After George's glasses are stolen at the health club, he walks outside and sees Anna kissing Jerry's cousin Jeffrey. At least, that's what he thinks he saw. Without his glasses, he just saw two blurs, one with a horse-face that he could swear was Jeffrey. Though an unreliable source, the seed of doubt is planted in Jerry's mind, causing discord in the relationship. As it turns out, what George actually saw was a homely policewoman petting her horse.
