You probe by taking your alien daddy finger and put some nice grease on it to make it slide better up the human holes. my favorite kind of grease is either rapeseed oil or greek yoghurt. Now you got some nice grease on your finger you take your UFO and fly to the nearest human this human is gonna be your victim and then you just bend him over and then give them a nice round of Greek yoghurt finger :) Thank you for listening to this course your now a qualified prober!
