The

No "Mad Men" for this week's Firewall & Iceberg Podcast? No problem, as Dan and I had tons of other things to discuss (so much, in fact, that we put off the "Boardwalk Empire" mid-season check-in for at least a week). We belatedly discussed "Sherlock," Dan watched "In Treatment" for the first time, we got our zombie on with "The Walking Dead," answered a bunch of reader mail and (at the end for the benefit of non-DirecTV viewers) previewed the fifth and final season of "Friday Night Lights." The rundown:

"Sherlock" -- 00:45 - 06:35
"In Treatment" -- 06:40 - 17:00
"The Walking Dead" -- 17:00 - 28:35
Reader Mail (on "Parks & Recreation," TV couples and the economics of American TV) -- 28:45 - 50:00
"Friday Night Lights" -- 50:00 - 59:30
