using PIC to act as button push

I've got a little device that has some pushbuttons on it, and an LCD
that lights up. The PCB has some room on it, and I want to add a PIC
that I can use to "push" the buttons on this. Once I do that, I'll
have the PIC cycle through button pushes in order to automatically show
the functionality of the device.

Any ideas on how I can do this?

The button traces are a standard two traces that interlock, but do not
touch. The conductive rubber button is pressed, and touches both
traces to complete the circuit.

How can I get the PIC to do that for me?
