Did you know that you can hire a plane to fly an advertising banner for less then $1000?
That’s a rather small price to pay for a special proposal… or a milestone birthday greeting… or a vengeful jab at the man who did you wrong!
For a few extra bucks, most of the aerial banner companies will be happy to keep the identity of the hiree confidential so you can get away with denying that you had anything to do with it.
Only one grand for revenge AND public humiliation AND plausible deniability? What a deal!
