Welcome to the first edition of our new video podcast (or vodcast), Previously on TV Squad! While we can't cover every story of the week, here are a few that interested me this week:

• Steve-O of MTV's Jackass on the red/yellow carpet
• Sean Penn as ... Einstein?
• A karaoke contest to get a How I Met Your Mother walk-on role (or is it a singing role?)

The video's embedded below, or you can download the file directly (Quicktime required). You can also subscribe to this vodcast via our feed or the iTunes Music Store.

Let us know what stories you'd like covered for next week, and we'll see what we can do. Hope you enjoy it!
