Random Hero 

A.K.A Ryan Dunn. A man in his late 20's willing to jump in vats of shit and or fish for the amusement of other. Is also willing to insert small toys into certain parts of his body for fun.
The Random Hero can also be likened to a garden gnome (albeit a cute one)

see jackass, jackass the movie, CKY, Viva la Bam or Haggard.

Random Hero 

A hero who fights anyone, anything, anytime, anyplace, anywhere and anyhow.
Like Mystery Science Theater 3000, A Random Hero has no control over when things start and end.

Usually battling a motley crew of baddies, Nothing is never normal.

Also, A Random Hero is the savior people dont count on being saved by.

Guy: You saved me...Who are you?
RH: Im Random Hero!
Guy:...I wanted Superman.
