The previous version of my blog had a post with the ROFLCOPTER ASCII text, and after a few months, it was the most highly trafficked post on my blog, and continued to draw over a hundred hits a day.

I'm putting them back up on this blog because my fiance said I was lame for not having a ROFLCOPTER on my blog =)
