In his original stint, he won two games before being stopped by the series finals, and returned for the first heat of the new series, where he lost heavily to eventual winner Scott Mearns. In his second run on the show, he won three games before once again coming up against the eventual series winner Mark Murray, although this time, Johnson was able to keep the game much closer, holding Murray to a crucial conundrum.
He returned to the show at the end of 2014, to face-off against Bobby Banerjee in a special episode entitled "Battle of the Bobbys".
