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''. :-)
a boy in love with a girl, continue to be in love with her and a girl
in love with a boy, continue to be in love with him, untill on unless
any external agent(brother or father of the gal) comes into play and
break the legs of the boy
