Display Global Products: 3 random products


I have developed my own marketpress theme and on my homepage I want to create a "Featured Products" section.

I don't want anything complicated, Just 3 randomly chosen Global Products (e..g the title, image, description, add to cart).

I am aware that mp_list_global_products(); will grab all of your global products in a messy way...is it possible to just grab 3 at random on every page load, without pagination?

What is the best way to achieve this?
