I saw a black guy riding a bike today. I thought it was mine, then I checked again and it was still chained in my basement.
I think I know what you're trying to say. what exactly are you implying?
I mean that I own this bike, but it turned out to be his. And he is still in my basement where he belongs.
While to you this is just a joke, it is one that a lot of people would think is sickeningly racist. Is this how you want people to think of you?
