Best 'small Successor'?

[Fluvius Camillus]

Wasn't the difference between sarcasm and irony, that sarcasm is being hurtful and irony more a fun way.

Example:

Irony:
Son comes home with his school results, all awesome grades. Dad tells: "Pff... Couldn't you do any better?"

Sarcasm:
Son comes home with the message he has to do the year all over again. Dad: Wow, you really did an awesome job at school, congratulations!

Sarcasm does have the element of mockery. Take for instance the comment that started this tangent "Internets is srs business." The author was commenting on how other posters were taking things too seriously and mocking them. Thus it makes sarcasm. In your too examples do you see how the sarcastic one is mocking or denigrating the the son where in your first example the dad is actually using irony to praise the son? There is your difference one is humor and the other while it can be humorous is mocking or insulting.
