Listen up, buttercup. The joke plays on the double meaning of "junk." Initially, you think it's about setting a record with, uh, personal anatomy. But the punchline reveals it's just about having stuff, aka "junk", in a library, which is a no-no. So basically, you thought it was gonna be a wiener joke, but it wasn't. Based, right?
