3 (tie). Happy Days (ABC)
It's no surprise that Happy Days — which tied with for third place in 1978-'79 — continued ABC's domination of the ratings chart in its sixth season. You've got No. 52 on our icons list, Ron Howard (Richie), accused of being the Kissing Bandit, and No. 32, Henry Winkler (Fonzie), faking his own death. You've also got that great multi-part season opener where the Cunninghams head to the dude ranch and Joanie (Erin Moran) finds herself on a runaway wagon.
