My cousin is about 18 months younger than me and his wife is the same age as my mother (who someone once thought was my wife).
They are as unhappy as any married/unmarried couple I know so who cares?
A sixteen year old is not a child.
If they can vote, get married and go to war etc then they can diddle and be diddled by muppeters.
Going by Elmo's voice I imagine the younger chap was 'bowling'.
