The fifth season of The Bob Newhart Show offers even more fun, laughs, and neuroses with Chicago psychologist Bob Hartley (Bob Newhart), his wife Emily (Suzanne Pleshette), the Hartley's airline-pilot neighbor Howard Borden (Bill Daily), Bob's dentist friend Jerry Robinson (Peter Bonerz), and Bob and Jerry's newly married receptionist Carol Kester Bondurant (Marcia Wallace). Some of the season-five episodes are among the series' best, and several are acknowledged classics in the situation-comedy field. "Caged Fury" is the one in which the Hartleys miss their neighbors' Fourth of July Bicentennial celebration when they're trapped in a storage locker; "The Slammer" finds Bob and his school buddy Cliff Murdock (Tom Poston) reliving old times and landing behind bars as a result; "Here's to You, Mrs. Robinson" focuses on the newly retired Jerry Robinson's efforts to locate his birth parents; "The Ironwood Experience" has Bob agreeing to give a lecture at a sex seminar, little imaging that his audience will show up naked as jaybirds; "Death Be My Destiny" is the famous "epiphany" episode in which Bob has a heart-to-heart with Death (played by series producer Tom Patchett) after nearly perishing in an elevator mishap; and "Desperate Sessions" finds Bob taken hostage by the nicest bank robber in TV history. The season ends with the "teaser" episode "You're Having My Hartley," in which Emily announces that she is pregnant. This was intended as the last-ever Bob Newhart Show episode, inasmuch as the star planned to hang it up after five seasons; however, at the last minute the series was renewed forcing the writers to figure out a way to "un-impregnate" Emily.
