Do I need resistors to limit current for simple push-button with ATmega32U4?

Paul H asked Sep 15,2020

If I wire a simple momentary push-button to an ATmega32U4 and am using the internal pull-up resistor, do I need an additional resistor to limit current?

According to the datasheet, the internal pull-up resistor is 20 - 50k so I don't think I need anything extra?
