Google analytics code showing on site

I have just add Google analytic code to my site and now at the upper left corner of my page the text:

\', \'auto\':wink:; gaplusu(\'send\', \'pageview\':wink:; gaplusu(\'require\', \'displayfeatures\':wink:;

Is now appearing. When I delete the Google Analytic code it is gone. Can you please help ?
