Santa's Birthplace

Santa was in a state of coma and an aged matron was taking care of him.
One day, the matron had to go on leave due to an urgent work. She called the young nurse and explained her everything about Santa and how to clean his private parts, including penis which had `Tram` written over it.
When the matron came back after her leave, the young nurse enquired the matron, "I did everything as explained by you but there is one thing which I could not undertstand.
You said that the penis had `Tram` written over but I noticed `Thiruvanthapuram` written on it."
