Welcome to the wonderful world of jugs.
The Jugs Machine- great for practicing your swings at various speeds and curves. Every worthwhile high school baseball program in the country has one of these so that the players can get their hacks in during those frigid winter months or on a rainy day. Also has been known to save many of coach's arms. Side note- Mike Piazza looks like a douche with that mullet and stache, doesn't he know this ain't the 80's.
Jugs- great for storing liquid substances like milk, water, or your favorite moonshine concoction. Where would the world be today without this revolutionary invention? Probably thirsty.
Last, but certainly no least, are my favorite kind of jugs...the ladies jugs! I love being a man. These jugs have many uses, as they can be used for feeding offspring, as pillows, or for pure pleasure.
