I don't really think trolling is an apt term for making jokes that only you (or in my case I) find funny

so in answer to your question what I do is practical jokes, they have to be good enough to be funny but not too good that the "victim" turns around and punches you in the face.

when I worked in an office I used to make motivational posters with peoples faces on them (people who worked there) with stupid things written under it like I'd have a picture of the office manager "Alan" and underneath I wrote "always striving for 3rd place"

this kind of thing requires imagination which you may well lack given that you're asking what to do on a questions and answers site.
