Here's why he is a bitch:
Around the mid-1980s, Johnson started a fast-food fish restaurant business, and became semi-retired from performing, only making occasional appearances at blues club gigs.

In 1992, Johnson found out that his song "Different Strokes" had been
sampled by number of
rappers including
Wu-Tang Clan,
Public Enemy,
Kool G Rap,
Hammer, and the
Geto Boys. Stimulated by this fact, he decided to make a comeback in the
music industry.
[1] In 1994, he released the album
Back in the Game on
Delmark Records. The album featured the Hi rhythm section and his youngest daughter
Syleena Johnson.
The dude retired and then because people were sampling his shit he decides to make a come back. If anything he owes the artists that are introducing his music to a new generation of fans some gratitude. If it wasn't for the "thieves" he would still be running a fast food joint.
