I just fucking think it 's horrible . [ Laughs ] I hate the opening riff . It 's what we call a ' happy riff . ' It 's just like ' la @-@ lala @-@ la @-@ la @-@ la . ' I can 't see myself playing it , but after that , where it get heavier , I like that section . If we ever did a medley , I 'd put part of that in there .
