Then why does daddy have two legs?

Today I took all 3 boys to the Hampton Pool. We had a great time! When we got there I told them the story of when Dylan was a week old and daddy was playing softball at the Hampton park and someone slid into leg and broke it. I continued to tell them about how daddy had to sleep on the couch so that he could keep his leg elevated and how one night he fell asleep holding Dylan and as he drifted into a deep sleep, his arm let go and he dropped Dylan onto the hardwood floor. Anyway, after I was all done telling the story I assumed the boys would ask questions or make comments about the broken leg or Dylan being dropped... but nope, the response I got was Cameron asking "But then why does daddy have two legs now?" I just started to laugh and explained "Daddy just had a broken leg ... it didn't actually fall off or anything." LOL
