In Bladtcast #156, "UB40, IB40", Agent Starling and Captain EO join Christian in studio for the first of three special episodes to wish him a happy 40th birthday with some surprise guests.

First up, Gene Barretta (AKA "Gene in Philly") brings a whole host of friends to share their birthday wishes, then Brad in Melbourne (AKA "Old Man Morin") shouts some birthday cheer from down under, and finally, a birthday chat with comedian Karl Zahn (AKA "Karl from New Hampshire").
