An inside unoriginal overused joke only guitar players will understand it is the tablature of the riff in the 70s rock song, "Smoke on the Water" by Deep Purple it is often regarded as the easiest guitar riff of all time that every guitarist knows. Most guitarists just refer to the song as "0-3-5" and think its funny to play everywhere and yell out "PLAY 0-3-5!".

(ngl though it does slap and is a banger song in general)
Unfunny guy in a guitar center: PLAY 0-3-5 BRO!

Whereas 5 0 refers to the police generally, Johnny 5 0 is slang for a specific cop- as in, the 5 0 are on their way to arrest you, but Johnny 5 0 is the guy who actually puts you in those cuffs.
I was walking down the street minding my own business, when Johnny 5 0 popped up outta nowhere and asked me for my ID. Naturally, I got the fuck outta dodge as fast as I could.
