Imagine you’re The Flash. Grab a slipper quickly. Do not bother if you should use the left or the right slipper. Aim. Throw it at the targeted roach with as much force as possible.
This is a guarantee you won’t kill that roach:
Scream. Think whether you should use the right or the left slipper. Throw the slipper in random areas repeatedly (throw, pick up slipper, throw, pick up slipper, repeat as many times as you can) hoping to pin down that roach. Watch roach scurrying out of the room. Scream.
That roach better be out of the house tonight otherwise it’s gonna get it!
