Knuckle Theory

A theory used by measuring the number of days in a month. If your index finger touches your knuckle of your hands, the month has 31 days, while if you touch the skin of your fist, it has 30 (with the exception of February).
Scott: Dude, how many days are there in August?

Dave: 31.

Scott: Isn't it 30?

Dave: Use the Knuckle Theory.

bloody knuckle fight

A type of boxing/street fighting with no padding. Both the knuckles and face bleed, so blood gets from fists to face and vice-versa. There is not an obvious winner since both persons involved are seriously injured on at least one part of their body. However, the person last conscious is usually considered the victor
X: I got in a bloody knuckle fight. My hands are all cut, one of my hands is broken, and so are three fingers on my other hand. Also I got punched in the face that gave me a black eye, and almost ko'd me.
Y: Damn, sounds brutal. You win?

X: Who knows. Both of our hands and faces were messed up and we were both punch drunk

Ex2:
X: I won a bloody knuckle fight with one hit, although that broke my hand
Y: you k.o.'d him with one hit!?
X: yeah, but my hand is shattered my hitting him in the face.

Knuckles the echidna

& knuckles & knuckles & knuckles & knuckles.
anyway, Knuckles is a red echidna and is the protector of the Master emerald. the master emerald holds all the power of all the other 7 emeralds. Knuckles is what people call a "badass". he doesn't care what people have to say and used to not get along with sonic because eggman tricked him into thinking sonic took the master emerald when really eggman did. knuckles has appeared in most of the sonic games since " Sonic the hedgehog 3 & knuckles". and he is also getting a tv show soon based off his role in the 2nd (actually 3rd cause of the ova) Sonic movie, which went to theaters in april 8 2022!
sonic: hey tails where is Knuckles?
miles "tails" prower: oh idk, he's either with rouge the bat or protecting the emeralds as usual.

knuckles: I'm over here Knuckleheads.
and I'm named knuckles the echidna.
