Doobie or Not Doobie (1)

The Doobie Brothers are set to put on a concert at the guys' high school and they leave Rerun to get the tickets. However, by the time Rerun gets to the ticket booth, they're sold out. Later, two shady characters offer Rerun free tickets if he just tape records the concert. It is only later that Rerun learns that they are bootleggers and they threaten Rerun, Raj and Dwayne if they don't comply.
