Disease?

Santa went with his wife on honeymoon and they were getting undressed together for the first time. Santa took off his shoes and socks and his toes were all twisted and discolored.
"What happened to your feet?" his wife asked.
"I had a childhood disease called Tolio."
"Don`t you mean polio?"
"No, tolio, it only affects the toes."
Santa then removed his pants and revealed an awful-looking pair of knees.
"What happened to your knees?" she asked.
"Well, I also had Kneesles."
"Don`t you mean measles?"
"No, kneesles, it only affects the knees."
When he removed his shorts, his wife gasped and said, "Don`t tell me, you also had Smallcox!"
