I don't have a juicer but I'd like one.
I make smoothies instead or fruit purrees...with yogurt in it.
The strangest combination I came across was yogurt, banana and orange. It sounds so simple but it develops a coffee arome/taste.

I don't even like coffee, but this is funny.
Usually I throw in all seasonal fruits, and sometimes also frozen ones. Especially raspberries, they are great with everything.
