A newlywed couple were on their honeymoon and were seeing eachother naked for the first time. The woman unclothed herself and laid her beautiful body on the bed. Then, it was her husband's turn.
First, he removed his shoes and socks revealing knotted and twisted feet. The wife asked what had happened, and the husband replied, "I had tolio as a child."
The woman asked if he meant polio, and he said, "No, it only affects the toes."
He then removed his pants and revealed deformed knees. He admitted, "I had kneesles too."
Finally, he pulled off his boxers. In shock, the woman gasped and said, "Oh NO!!! You had smallcox too!!!"
