LMAO. I did a rick roll once, but only because it was appropriate. It was on dude_se's birthday a few weeks ago. I wouldn't do it to anyone else..just him because of his avatar hehehehe.
i remember i posted some link to somewhere where everytime you tried to exit your tab or window it wouldn't let you by giving you like a jillion popups and you would have to end the process lol but i remember warning everyone about it when i posted it lol
