I saw that "It was Meg's fault for Brian getting hurt" joke from a mile away.
It was a very good episode from later seasons' standards, but I actually enjoyed Meg's plotline more as it was much more original.
For Brian's plot, we already saw someone becoming a singer at a lounge ("Mind Over Murder"), we already saw a near death experience change someone's life ("Stewie Griffin: The Untold Story"), we already saw Brian going wacko ("Thin White Line"), we already saw Brian & Stewie being best friends ("Road To Rhode Island," "Road To Europe," "Peter Got Woods," among others), we already saw Brian hanging out with famous people ("Brian Does Hollywood"). Lame ass plot. I know Seth loves classic music but enough is enough. This should have at least been the subplot.
