Outside the Lines With Rap Genius - OTL 46: Ron Isley Excerpt #5 - Contagious lyrics

SameOldShawn: I will literally get fired if I don't ask you about "Contagious." It is my boss' favorite song in the whole world. He wanted to know everything about it, but in particular that ending line about, "I'm gonna catch a case," where that came from Ron Isley: R. Kelly. Now, you know what? I have to admit this. When I sang the song, I didn't know what "catch a case" meant. I would do it on the stage, and everybody would scream. And I'd say, "What are they talking about? Catch a case of claps? What are they talking about, catch a case?" It was a funny way when they came up to me and said, "'Catch a case' means catch a case in jail. You catch a case, that means you gotta go to jail, you caught this case." Maybe that should be something I shouldn't even tell, you know? And so R. Kelly just fell on the floor laughing at me
