Awesome / Welcome Back, Kotter

• At the end of "Chicken A La Kotter", Kotter walks out after one too many nasty comments from his boss. He and the Sweathogs take their chicken and leave...but not before Arnold goes back in and puts the head of the chicken costume on the boss's head.
• Horshack talking down the suicidal Mary Johnson. In return, she saves his life when he slips and nearly falls off the same ledge she tried to jump from.
