The tower was having some difficulty working a student pilot in the pattern and it finally came down to this;
95 Delta, do you read the tower?
95 Delta, Say Again
I think it is 675.
95 Delta, What do you mean by 675?
I mean I think I read "Elevation 675 feet" on the tower as I taxied by for takeoff, but I am too far away to read it now.
95 Delta, you are cleared to land. Please give the tower a call ON THE TELEPHONE after you have tied down.
