Height of frustration:
Your parents ask you if you have a girl friend and they are ready to marry you with her. But you realise that you never had one.
Height of resemblance:
A friend (male) asks another friend how does your girl friend look like. In reply the other guy says (..very seriously..), she looks just like you.
Height of insult:
A guy is standing at the corner of a street. He finds a pretty girl across the street. He finds the girl approaching him. By now this guy has made up his mind that this is the girl with whom he can spend the rest of his life. All of a sudden he gets a knock from the twisted fate. The girl asks him - Uncle, wot's the time?
