No seriously, I did give a black man watermelon flavored beer once.  He was jokingly giving me shit for offering him chicken (he asked if I had any food that he could heat up, and chicken was literally all I had at the moment), then started jokingly going on about how I'm going to offer him watermelon next, I then jokingly offered him watermelon flavored beer, and he went "oooo, can I pocket one of those?".  We had a good laugh, and he got a free bottle of beer.

I enjoy experiences like that.  And yes, watermelon flavored beer is a thing.
