I'll make an exception for BHOP simply because it's BHOP. Any Mike Tyson entrance is ok as most of the entrances are usually longer than the fights. For everyone else? Nope. Stick to boxing. I know it's promotional and you're selling the event, but Naner12 hit the nail on the head. When you come to the ring with all that flashy shit, get knocked out and carted off to the hospital then what?
