On another post I was reminded that words if incorrectly spaced can meaning something completely different and I guess this applies well to domain names where spaces do not exist. This can lead to some unfortunate urls. I wonder which domain you have had a good chuckle to, here are some domains I have come across (they are actually real)

www.whorepresents.com (who represents)

www.penisland.net (pen island)

www.therapistfinder.com (therapist finder)
