How did an intelligent boy propose to a girl? He took the girl along with him on a boat n at the middle of river said ''Marry me or leave the boat''. :-)
Girl: when we get married, i want to share all your worries, troubles and lighten your burden..
Boy: it''s very kind of you, darling, but i don''t have any worries or troubles..
Girl: well that is because we aren''t married yet....
