Kristen Hanby has laughed off rival Vitaly Zdorovetskiy's prediction of a first-minute knockout in their fight on Saturday night.
The YouTube pranksters will trade their video cameras for boxing gloves at the OVO Arena Wembley this weekend when they make their boxing debuts, and Hanby will be looking to overcome a substantial size difference to get the best of the Russian.
Zdorovetskiy told Mirror Fighting in the lead-up to the fight that he was planning to stop the Brit within not just within the first round, but the opening 60 seconds.
