No it wasn't pointless!
short and funny- it was exactly as you described it and in a very sick way it made me laugh.
The animation was everything it needed to be and the art was OK.
The voice acting was fine and the sound was clear.
I would make the music slightly quieter, personallym although there was nothing wrong with it.
It would be nice if you put in a background- a park, a playground, whatever.
I thought there was a couple of levels of humour there- I mean, the opening question - are you...? as if there was any doubt!
and Dodgeball...as if!
then the legs waggling in the air!
