After you spend forever jamming a stupid little electric buzzer up your nose to trim the hair, the one or two really long pieces of nose hair that mysteriously escaped the razor and sneak out of your nose untouched later in the day.
Bro, I know what your saying is important, but I just can't stop staring at that really long hair coming out of your nose. It even wiggles a little when you talk... Why don't you trim that shit?
I tried, but those god damn Nose Ninjas are so sneaky!

2) Install random rotating magnets. This makes it difficult to throw shurikens accurately.
