I first saw David Costabile as Mel's submissive husband on the hilarious Flight of the Conchords. It was a small role, but merely a sign of things to come.
I then saw him in Season Five of The Wire as Managing Editor Thomas Klebanow. The Wire, as you may know, is my favourite television series of all-time. Again, it was a pretty small role, but it was pretty cool seeing someone from FotC on The Wire.
Then, while watching one of my favourite shows since The Wire, I saw him on Breaking Bad in a pretty juicy role. He was Gale Boetticher, and I won't spoil anything by telling you about Gale Boetticher.
For playing a recurring character in Flight of the Conchords, The Wire and Breaking Bad, I thought David Costabile deserved a little praise.
