Dance fever Take a stroll (or a cha-cha) down memory lane as "So You Think You Can Dance Top 15 Dances" (7 p.m. KMSP, Ch. 9) looks back at the best 15 performances over the past five seasons. As a bonus, German shepherds will share their reactions to judge Mary Murphy's top five shrieks.

Getting ahead Doesn't Neil Patrick Harris, right, have enough to do? The host with the most (gigs, that is) joins the rest of the cast of "How I Met Your Mother" to offer sneak peeks of some upcoming new series' during the "CBS Fall Preview" (7:30 p.m. WCCO, Ch. 4). Looking for a more, um, objective take on the network's sked? Make sure to check out the Strib's jam-packed, fall-preview package this Sunday. Shameless plug concluded.

The brave one The art of letter writing may be dying, but the art of letter reading is alive and well, at least when done by high caliber actors such as Michael Douglas, Nathan Lane and Joan Allen. It helps that the all-star cast members are reciting the words of Dalton Trumbo, the award-winning screenwriter who watched his career go off the rails when he was blacklisted. "Trumbo" (9 p.m. KTCA, Ch. 2), a new documentary under the "American Masters" banner, captures the brilliance and bitterness of the man behind "Spartacus" and "Roman Holiday." Paul Giamatti's recitation of a scathing note Trumbo wrote to the phone company is a particular treat, one that forever raises the bar for all form letters.
