Humour found in piano works

[cuberdrift]

What composers, and if so, which of their pieces, utilized a sense of humour? I find a part of the second movement of Mozart's K281 (Sonata in Bflat Major) to be potentially done in humor - the right hand is occasionally accompanied by a loud octave in the lower register by the left, interrupting the "serene" nature of the right with a kind of harsh and crass interruption. Could it have been coincidentally funny, or did Mozart really want to give people a laugh?

What do you think?

this always made me chuckle while performing it, almost laughed out loud at my jury  

really great alternate inerpretation, the quicker tempo does give it fun bouncy sense

this one is funny too, also from my past, especially some of the unxpected harmonies (ear expects a certain progression and Luddy sticks his tongue out at it and gives us the unexpected)

Mozart joking as always.
Also Zimerman is the best
