“Conjunctivitis.com—that’s a site for sore eyes”

A “(web)site for sore eyes” is a pun on the expression of a “sight for sore eyes.” English comedian Tim Vine has been credited with this joke since at least 2009:
   
“Conjunctivitis.com—that’s a site for sore eyes.”
     
The domain name Conjunctivitis.com does not appear to be active.

I’ll tell you what, never again” and “I decided to sell my Hoover ... well it was just collecting dust.” He was the runner up in 2011, 2012 and 2013.
 
Wikipedia: Conjunctivitis
Conjunctivitis, also known as pink eye, is inflammation of the outermost layer of the white part of the eye and the inner surface of the eyelid. It makes the eye appear pink or reddish. There may also be pain, burning, scratchiness, or itchiness. The affected eye may have increased tears or be “stuck shut” in the morning. Swelling of the white part of the eye may also occur. Itching of the eye is more common in cases due to allergies. Conjunctivitis can affect one or both eyes.
