Paulie and the boys hit the hardwood for a game of hoops against the guys from OCC Ironworks in what can only be described as a comedy of errors. But back in the shop, it's all business: Big Paul blows up at Vinnie for leaving the shop in disarray and nearly sends him home for the day. However, once Senior gets a look at the Miller Bike's patriotic paint job and the outrageous tow-behind welder, all is forgiven.

The Teutuls go Hollywood when Tonight Show host Jay Leno commissions a modern version of his favorite classic bike: the 1939 Brough Superior. But back at OCC, the excitement fades when Paulie discovers that the bike's frame is too small to accommodate the oil tank. And when the motor and wheels arrive late, it creates a host of technical difficulties that threaten to put the Leno Bike on hiatus.

It's crunch time for OCC as they press to complete fabrication and assembly on the Leno Bike project, but when thicker-than-usual powdercoat slows down Paul Jr. and Vinnie's progress, can they get the bike finished in time for its Tonight Show debut?

How do you honor the greatest monument in American history? You build her a custom chopper, of course! And that's exactly what happens for OCC when they get the task of creating a bike that symbolizes American freedom and the Statue of Liberty, with one of Paul Jr.'s daring ideas to date: coat the entire bike in Statue of Liberty copper.

The Liberty Bike quickly goes down as the hardest bike ever to assemble and finish when parts go missing, and Paul Jr. having to reject Mike Campo's Statue of Liberty face fender.

With Junior and Senior heading out of town to be on The Tonight Show, Mikey and Vinnie get the opportunity to create their own one-of-a-kind chopper and the good times come to a halt when OCC's new Director of Operations, Keith Quill, expects the bike to be finished in time for a New Orleans bike show around the corner.

The Mikey/Vinnie Bike steadily reaches completion, despite Keith acting like Paul Sr. and sending Mikey home for being late for work. The hard work pays off when the bike is ready for its debut, with one small problem: It won't start.

But throughout the build Senior struggles with problems, from Paulie showing up late to work to never-ending fights with Mike. Then, after a trip to the dentist leaves Mike in an anesthetized stupor, Senior and Rick are left to work on the handlebars without his input. Will his empty spot slow down the build, or will Senior and Rick survive on their own?

The David Mann tribute takes on new meaning for Paul Sr. upon learning that David Mann passed away. More problems emerge when Paul Sr. gets fed up with JB Graphix taking too long with the paint job and not getting it right the first time.

Will they get things together and finish the bike before their fast-approaching deadline?
