Replying to Some kid added me to msn

and he claims that i added him, which i didnt because i got an add from him, and i looked up his email on facebook and hes some kid from a city i used to live in and knows some of my friends. Anyway hes telling me hes in some band and i looked them up and they obviously dont exist. but hes pissing me off cause hes making up so much bullshit, i dont understand why he wouldnt just add me if he knows who i am instead of making up some fake email and telling me lies, whats the point?
Whats something funny I could do to him?
Or should I post his email and everyone add him to screw around with him?
