Mistaken identity: good_stuff from Germany

Strange.
This Girl sends me a big mess of "hi"-"hello" messages on Yahoo!IM this weekend. All of them offline messages, of course, since, before today, I haven't logged into my Y!IM account since August. I have no idea who she is.
I respond with a polite: "hi... do you know me? or are you just randomly msging people?"

This I get this:

good_stuff : well u told me to look at ur pic im truelovin from migente mr.
blue_j: migente mr?
good_stuff : yeah
good_stuff : dont u remember
blue_j: i don't know what migente mr is... I'm thinkin' you got the wrong screen-name
good_stuff : nooo now i know u send me one on my e-mail
good_stuff : im sorry
blue_j: np,
BUZZ!!!
good_stuff : yes u did wait
good_stuff : u told me ur father was station in germany
blue_j: nope, that wasn't me.
blue_j: sorry.
good_stuff : oh whatever i have ur messege right in front of me
good_stuff : u wher on the octoberfest and u order a hamburger and the women brought u a a big burger like from the flintstones
blue_j: nope, I'm really sorry, but that's not from me. Does it say it's from blue_j or blue_j@yahoo?
good_stuff : well i dont know
good_stuff : it dont matters anyway
good_stuff : im sorry
blue_j: no prob.
good_stuff : ok bye

Does this happen to anyone else?
Also, should I have played along? I mean, her userpic was cute:
