Use a pull-down resistor of course.  If you don't do that you should set
the pin to output a low for several instructions, then set it back to
input and read the read the pin immediately, so it doesn't have time to
drift back toward a high level. You may not read high properly then
though.  Connecting a capacitor from the pin to ground would make it
float around more slowly.  But if you use an external component it should
be a pull-down resistor.
