Alert : Facebook - 10 lies girls tell guys.. not a good application to have!!

I use facebook to connect with my friends. few days back i received an applciation invite named "10 lies girls tell guys.." from a friend of mine. since it was from a trusted person and titile is catchy,i decided to try this app.
but to my surpirse, when i opned the application it gives and window with instruction like : press ctrl + c then press alt+d then press ctrl +v after that press enter.
well it seems stranged to me so i followed this instrution and decided to see what it does. so ctrl+c copied some code to the windows clipboard,then alt+d selected my address bar and then ctrl+v pasted that code.
well i have not clicked enter yet but that code and the procedure of clicking ctrl+c and alt+d etc is somewhat i feel was suspicious.it seems that this application is now removed from the facebook and is not accessible.
so beware if you got any such email from your friends.
