For a while, it seemed like every stand-up comedian got their own sitcom.
Then, they all got talk shows, and celebrities were so worn out running from show to show, they had no time or energy to do all the stuff that made them celebrities in the first place.
The guests dried up, the audiences dried up, and finally the advertisers dried up.
The comedians lost their talk shows and tried to get sitcoms, but the sitcoms were all replaced with reality shows.
So, they started their own comedy clubs, and the young comedians flowed in… with their sitcom dreams.
