Online posts for "trolling" doesnt impress many people.
Troll wallmart and prank call them, put that on youtube,, and include your username from here and you will have a resume for people to admire your work!

I would pay for an actual series of phone call pranks, uploaded to youtube so I can enjoy it..
and I would pay Hmmm..  about 0.01 per minute of hearing that person.
You could call them back as often as you want.  Dialing the phone doesnt count, time counts when they are on the line with you.
Max up to 100 minutes worth for me to check out your work.
That is many times more than minimum wage.  Considering the post call video edit + upload effort I believe that is very fair.
Minimum wage is like $10USD or so. 
I would double it if you make them scream (Which would be near impossible to do as they are a professional at a workplace.)
