wedding woes

A married couple is about to have sex for the first
time on their wedding night. They start to undress,
and the husband removes his shoes. The wife notices
something frightful about his feet. "Oh my goodness!
What happened to your toes?" she exclaimed. "I have
tolio," he said. "You mean polio?" she asked. "Well,
it's kind of like polio except it only affects your
toes." The husband then removes his pants. "Oh my
gosh!" the wife exclaimed again. "What happened to
your knees?" "I have kneesles. It's kind of like measles
except it only affects your knees." The husband finally
takes off his underwear. The wife says, "Wait, let
me guess, smallcox."
