Shuffle values in userform textboxes

Hello, I've been trying to rack my head around this problem for a few weeks now and haven't got anywhere near a solution.

I have a userform with 5 textboxes (for names) and a "shuffle" button. After the user has added names to the 5 textboxes, I'd like them to be able to press the shuffle button which would randomise the names across the 5 textboxes (i.e. the name in box1 moves to box4, etc).

Is this possible to do?

Thank you.
