Messy, but possibly useful. Has lots of links to oddball websites like "Pun of the Day." "Refdesk is only about indexing quality Internet sites and assisting visitors in navigating these sites. At Refdesk that is all that counts and that is all that will ever count. Since 1995, Refdesk free and family friendly. Avaritia facit Bardus - Greed makes you stupid."
