My brother keeps taking naked pictures of himself and is hiding them under my pillow?

Well it all started when Michael Jackson died so he looked up more about Michael Jackson because he was so distraught about his death so when he looked up Michael Jackson he saw a naked picture on Michael Jackson and he wanted to have a better body than him so he went to netto and got some Vaseline and put it on his body and has been taking pictures of himself and is sending the pictures under my pillow with kisses on them I don't know what to do?
