Get the Ninja Facemug. Setting up your house to ward off long term ninja infestations. It's considered impossible to keep ninjas out entirely. In fact, attempting to do so can attract their attention and just make the problem worse.
1) Coat the walls and ceilings with steel backed teflon. If the steel isn't thick enough, they can still use their claws. Make sure it's at least a 1/4 inch thick.
2) Install random rotating magnets. This makes it difficult to throw shurikens accurately.
3) Set up a DVD of old "Kung Fu" reruns in infinite reply. Warning: This may cause Seppuku incidents, which are really messy. Take my word on it. Spread plastic in front of the TV.
Avoid using pirates. I know it's tempting, but they're worse than ninjas (really loud and smelly and treasure chests are hard to find).

Get the Ninja Proofingmug. A vehicle that appears out of thin air, completely parallel to your car, the moment you start to change lane.
I tried to change lane, looked in the mirrors and everything, but as soon as I started, a ninja car suddenly WAS there and blocked me. It came from nowhere!

Get the Ninja Carmug. Something you say when you've taken too many hallucinagins and intend to say something else, but unfortunately you have word salad.

Get the spasm ninjamug. 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!
