any satie, but especially the random ones which describe lanterns swinging, and shellfish mourning etc. Love those, they are so fun, and confuse people!
Also fun (when its been practiced!) is the minute waltz, love that as grew up with it on radio 4 and so pleasing when it goes well.
I also find clementi fun, it is very pleasing.
And some of those mikrosmos, like 'buzzing', I like that random stuff.
