Definitely not.
I switched from JB&B to FBHW when they came to 102.9. On some of the days they have Best of shows I've tried to go back and listen to JB&B and I just can't do it.
True story I found an old cassette tape at my parents last Thanksgiving and took it home. I put it in my last working cassette player and it was about 2 hours worth of a JB&B show from May 1998. I listened to it and then the next Monday I listened to an hour of JB&B and aside from some of the current references in the 1998 show, you really couldn't tell each show was 10 years apart. The same type skits, same games, same songs played....made me realize just how stale JB&B has become.
