I was walking my dog just now and this random guy in black clothing proceeded to ride up the street, and repeatedly hit the street with a mop while riding the bike... Like he was swinging the mop around and barking. So my dog hears these sounds and she starts barking. The guy starts looking around for the dog barking back, he didn't see me or the dog because I was around the corner, so I could see him, but he couldn't see me. so I grab my dog and turn around back to the park because I am having none of that. Eventually he even started howling. I'm not making this shit up. I actually got kinda worried at that point. Luckily a cop (well, parking enforcement) was driving up my street at the same time so he looked back at the cop car heading for him and just sped off down the road swinging the mop at the street. So I turned back and headed home...looking out the window he's just riding around the block hitting the street with a mop...I think he's still looking for the dog 0_0 TL;DR I encountered an unlicensed street cleaner. (That was a joke, but the story isn't.) What is even happening on my street right now?
