Childhood illnesses

So this couple are in the Honeymoon Suite on the first night of the honeymoon. The groom sits down and removes his shoes and socks (as you do).
“Oh” says his bride “Your toes are all shrunken and small”
“Yes - I had toesillitis when I was a boy”
“Dont you mean tonsillitis?”
“No, my love, I do mean toesillitis, it leaves you with very small toes”
The Groom then drops his trousers.
“Oh” says his bride “Your knees are all shrunken and small”
“Yes - I had kneemonia when I was a boy”
“Dont you mean pneumonia?”
“No, my love, I do mean kneemonia, it leaves you with very small knees”
The groom removes his underpants and his bride comments,

“I see you also caught dicktheria!!!”
