CM Punk
During his walk-on in his second-round match against Raymond van Barneveld in the 2011 World Matchplay, Nicholson mimicked former WWE wrestler CM Punk by having X's marked on his hands, and also lifted up a Nexus scarf. However, he lost the match, 13–9. Then, when he met Phil Taylor, he once again mimicked CM Punk during his walk-on, using his signature pose on one knee, shouting "It's clobberin' time" and punching the air. During Taylor's walk-on, Nicholson sat Indian-style on the stage, another trait of CM Punk, in an attempt to anger Taylor.
