Fellowship of the Blimp

"Good morning erbo."
"Who is this?"
"This would be Sambob."
"Sounds familiar.. so, what?"
"Do you know what i do for living?"
"No, i have never met you."
"I'm a secret agent."
"Pfft, hah!"
"Yes."
"Wait.. you're serious?"
"Yep."
"Uh.. what do you want?"
"We want you, to work for us."
"Really?"
"Yes, really"
"Cool, uh..what do i do now?"
"Close the phone, and turn around.
Instructions should be there."
*Beep Beep*

You don't really believe this Sambob, but still you turn around, and see a note hanged on your door.
You run to door and watch around for the person who put that there.
You see no one.
