Today is 'Won't You Be My Neighbor' Day

Today is the second annual "Won't You Be My Neighbor?" Day, created a year ago by friends and colleagues of PBS kids' show host Fred Rogers to mark what would have been his 80th birthday. So put on a sweater, and be kind to your neighbors. ... WGN Channel 9 airs the locally produced special "Circle of Care: Living With Diabetes" at 6 p.m. Saturday.

Therapy party

Alexandra Wentworth returns as a highly unconventional therapist in "Head Case," an improvised comedy (think of a live-action "Dr. Katz") on Starz at 9 p.m. today. It's followed at 9:30 by the debut of "Party Down," a new comedy from "Veronica Mars" creator Rob Thomas, about an El Lay catering team.

Chuck amok

Turner Classic Movies premieres the fine new documentary "Chuck Jones: Memories of Childhood," a profile of the Looney Tunes writer-director, at 7 p.m. Tuesday. It will be followed by a cartoon marathon peaking at 8:30 p.m. (and again at 12:30 a.m.) with "Duck Amuck," his classic Daffy Duck short that toys with the very form and structure of animated comedy. Don't miss it.

Pot o' sliders

Stoner comedies don't come any purer than "Harold & Kumar Go to White Castle," in which a couple of ethnic space cadets get the munchies, with predictable results. It's not quite as politically charged as the sequel, which travels to Guantanamo Bay, but it's more of a romp, at 6 p.m. Saturday on Comedy Central.
