Wait.... did Neil change his voice? No, silly. It's our friend David who dropped by to hang out and watch the Val Kilmer epic Top Secret (which Brian has been harassing Pete for months to watch). It's a throwback to time when movies didn't need much to get green-lit. A time when no one cared about plot holes. A time when the leading actors didn't need to know what was going on or why they were on set or in any particular scene. 

ahhhh.... the good ol' days.
