Do you even know what retarded means?
Step 1: Get a pic of a random guy playing the guitar from google, which apparently you don't know what it is, so I'll link you: Google
Step 2: Edit it and use it as your avatar.
Step 3: Use original pic as avatar and claim that to be enough proof.
Yup you're retarded. If you put it in tinyeye it would show up as no results. You just proved my point. Good luck finding it on Google. Retard.
