On today's Howard Stern Show, Howard was talking about how people approach him at parties saying Gary Dell'Abate won't allow him on the show anymore. However, we all know that Stern only does boring interviews with A-listers nowadays.
Robin said the same thing happened to her at a party. Tommy Chong approached her saying Gary won't allow Cheech and Chong on the show anymore.
Keep in mind that Howard Stern reunited them on his channel 9 show, back in the day (1991) and a few times since them. Cheech and Chong aren't a great interview and they're not A-listers.
