The newly married couple

A young couple left their wedding reception, arriving at the hotel for the first night of their honeymoon. They cracked the champagne and began undressing.
When the bridegroom removed his socks, his new wife said, "Your toes look all mangled and funny."
"I had tolio as a child," the husband replied.
"You mean polio?" she asked.
"No, the disease only affected my toes."
The bride was satisfied with this, and they continued undressing.
When the groom took off his pants, his bride exclaimed, "What's wrong with your knees? They're all lumpy and deformed!"
"As a child, I also had kneasles," he explained.
"You mean measles?" she asked. "No, kneasles.
It was a strange illness that only affected my knees." The new bride was satisfied with this answer.
As the undressing continued, her husband removed his undies.
"Let me guess," the wife said. "Smallcox?"
