According to the January issue of Harper’s, “One third of male Londoners suffer from penis blindness.” WITHOUT USING THE INTERNET, please participate in this impromptu poll.
The answer is below the jump.
The correct answer is, “The inability to see your own penis over your stomach.”
That is, unless you have any better ideas.

Penis blindness (or Lackanookie in Hawai’i) is caused by long periods of sexual abstinence. Dick don’t care what it look like, he goin’ in!
I cheated on this test.
I HAD A HIGH SCHOOL HISTORY TEACHER WHO REFERRED TO IT AS DUNLAP’S DISEASE….WHEN YOUR BELLY DUN LAPS OVER YOUR BELT.
HE WAS THE WORST.
Why would my penis be over my stomach?
