(S01E06) It's always a pleasure to watch nerd for hire Kevin Weisman stammer his way through a guest spot on a great show. I loved him as Marshall on 'Alias', enjoyed his stints on 'Moonlight' and 'Roswell', and who could forget his brief appearance as 'Hobbit Lover' in Kevin Smith's 'Clerks II'?

Weisman literally played a nerd for hire in this episode. His character, Martin Gleason, was a brilliant weapons engineer in need of a little rescuing. The twist, of course, was that his own company was holding him prisoner. I guess that's what happens when you're in possession of damning intel that can bring a powerful weapons developer down for good.

'Lockdown' was another fast and fun hour of 'Human Target', a show that literally orders viewers to turn off their brain, sit back and enjoy the implausible ride.

'Human Target' (Wed., 8PM ET on FOX) is crazy-fun for lots of reasons, not the least of which is outstanding guest stars.

In tonight's episode, we had Kevin Weisman, whose vast TV credits include 'Alias' (he's cornered the market on computer geeks), as well as Mitch Pileggi (Walter Skinner on 'The X-Files,' among dozens of other roles).

Between those two and star Mark Valley -- and let's not forget Chi McBride and Jackie Earle Haley -- that covers just about every show in the past 20 years, doesn't it?

Watch the video after the jump.

(S01E11) "Why do people hate the rich?"

So I guess it's official -- Chuck is actually in love with Sarah. I know it's what the show has been heading toward but, when Chuck briefly dated Lou, I thought he was finally coming to terms with the reality that he and Sarah will never end up together. Now it looks like he's ready to go all Scarecrow and Mrs. King. As Casey would say, "(Grunt)."

I know, I know, it seems like this is Columbo week here at TV Squad, but you've got to watch this. It's a video made for the 50th Anniversary of ABC a couple of years ago. I didn't watch the show, but I'm glad someone put it up on YouTube. Columbo has been called in to help Sydney, Jack, Vaughn and the rest of the team.

Who asked him to help out, and what is he supposed to help with? Well, you'll just have to watch it to see. You don't usually see a crossover episode involving two of your favorite shows, so this was a great find. Very funny stuff.

As part of the run-up to the series finale of Alias, seasons four and five of the show are now available on iTunes. You can buy one episode for the usual $1.99 or you can buy all of season four for $34.99. And, for the rest of the season, new episodes will be available the morning after they air.

Alias returns tonight for a two-hour episode from 8 pm to 10:01 pm (thus, no Lost).
