97. Mrs. Hamilton
Best-known episode: "The Millennium"
Speed dials were a new thing in the Nineties, but they were already a tricky dating issue. When Jerry climbs to the Number One spot on the speed dial of his girlfriend Valerie (a not-yet-famous Lauren Graham), her jealous stepmother Mrs. Hamilton jumps into Jerry's car to interfere. (Like much of the episode, this scene is a brilliant twist on The Graduate.) "Jerome, I have a deliciously naughty idea — why don't I put you on my speed dial?" Sadly, actress Louan Gideon just passed away in February. Here's to you, Mrs. Hamilton. ROB SHEFFIELD
