We know people we dislike & some that we detest
A simple trick to annoy the hell out of them is to call them several times a day, for several days, using various regional accents (and using a withheld number) asking if they can speak to [insert random name here]. After a week to 10 days of this call one last time & simply say "hello this is [random name] have you got any messages for me?"

Not that I would *ever* advocate this. Oh no.
