On Top Of Strawberry Hill

There were three guys who were late to class. The first guy came in and said, "Sorry I’m late teacher I was on top of Strawberry Hill". The second guy came in and said, "Sorry teacher I was late and it won’t happen again". Then the third guy came in and said the same. Then a girl came in and the teacher said, "Let me guess, you were on top of Strawberry Hill too huh?" The girl said, "No, I am Strawberry Hill".
