Description
Rick gets a visit from Grammy-winning singer-songwriter Jason Mraz, bringing in a sign to be restored in honor of his late grandfather. Will this project hit all the right notes or will Rick be singing the blues? Later, the crew converts a classic gas pump into a kick-ass "keg-erator." Can Rick create a macho beer machine or will his ideas get tapped out?
