As far as rick rolling people goes, my favorite trick was to hype something up in a post and post a link to the address given above. When you insert the link it leave you a highlighted portion that you can insert any words, etc. Best method I can think of would be to insert an actual address that relates to what you have hyped up but have it link to the rick roll. Something like this:
Guy I just want to tell you that I filled out this electronics survey and they sent me a free digital alarm clock! Completely free, did not have to pay for s/h or anything.
