Weird..i've never noticed an ad with sound from this site( I'm using Firefox 2 but i haven't installed adblock). Only time i heard a sound while surfing here was when Ben embedded the Metal Gear theme in the Smash bros thread. Had about 20 tabs open and it drived me crazy trying to figure that out.
Most irritating add that i've noticed(not here) was one advertising new emoticons that couldn't stop talking.(example: angel face: "oh behave!" cry repeated times infinity.)
"You won't find Adobe here in Nairobi"
