Tuba Keg

S1, E3: It's a new box with three more random objects: an electrical wall plug, an ice cream cone, and a sousaphone (which everyone mistakes for a tuba). Bob takes the sousaphone to a Bavarian Beer Hall where he builds something that channels the German traditions of good music and great beer. Thankfully he doesn't incorporate lederhosen. Next, Bob doubles efficiency at a gelato shop with an invention he makes on the spot. And with the wall plug, Bob devises a machine to keep order in his shop in a very unconventional way.
