Originally, somebody had the phone number 8.

Unfortunately, he kept getting calls from interns who would simply give him weather updates.

"It's sunny out" *hangs up*

"Quite bright outside today!" *hangs up*

"Very warm today, with blue skies!" *hangs up*

Eventually the man was forced to change his number, but it was his fault, really. He should have known that when it gets bright out your pupils dial 8.
