Honestly, there's a BBQ sundae at the NC State Fair and it's one of the best things you can get. Pulled pork, topped with baked beans, topped with slaw and barbecue sauce, all in a convenient carrying cup. No downsides, 11/10, would recommend.
I can't honestly tell if this is real or fake. I feel very strongly that I've seen something similar advertised at a U.S. fair in real life, so I wouldn't discount it.
