The show focuses on athlete Brady Kelly and actor Cheeks who find themselves married after a drunken night in Vegas. The second season picks up on their domestic journey as they learn to how to stay together. (Catch up on the hilarious first season here, which includes a cameo by Nathan Fillon.)
Let's take a look at those cameos again... While most came from the world of Joss (Buffy, Dollhouse, Dr. Horrible), a few came from Jane's world of TV (BSG and Caprica).
