Quest for the Holy Grail (S07E07)

While in California, Frank dives into Knucklehead Zen during a visit with an enigmatic international figure. Back in Maryland, he becomes fixated on a 1939 Plymouth Coupe and finds himself willing to shell out a fortune for it, despite the owner's reluctance to sell. In Massachusetts, he sweats it out while revealing a treasure trove of oil cans that he can't resist. After purchasing a massive Mississippi Riverboat artifact from a photographer in Wisconsin, Frank is filled with dread when it’s appraised upon his return home. He also hopes to dazzle his old classmates at his high school reunion with his new acquisition, but things rarely go smoothly.
