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)
