Roger and his friends sat around and watched the pre-season football game. Roger felt a bit of an itchy bum and walked out of the room to give it a quick dig and scratch. Instead of washing his hand and fingers, he returned to the room and swiped is nasty Mung Finger under one of his buddy's nose.

Euron: “...A finger in the bum?”

Kids, ever have parents walk in on you when you're supposed to be doing homework, instead you're playing a full-screen game? Adults, ever had a roommate/spouse/friend walk in on you as your viewing a hot A2M porno? Well then, you gotta employ some ninja fingers!
Mom: Timmy, are you doing your essay?
Timmy: *Alt+Tab* Yes mom, i am!
Rick(walking into Dick's room): Hey, did u catch the game last night!?
Dick: *Alt+F4* Yeah dude, that was awesome!
They both used ninja fingers to protect themselves.
