That wasn't after sentencing but happened last year and with a reason.
The comedian and creator of "Fat Albert and the Cosby Kids" filed paperwork in May -- about a month before his sexual assault trial began -- to renew the rights to the title of his animated series ... and the terms "Fat Albert" and "Hey hey hey" specifically.
Cosby wants to churn out t-shirts and DVDs featuring the cartoon ... whether he's a free man or not. Prosecutors vowed to retry him.
This also might explain why Cosby -- to the dismay of many -- shouted Fat Albert's catchphrase as he was leaving the courthouse during his trial. It was just marketing.
