The shows when Ant was out and O&J had Jay Mohr and Ronnie B fill in.
The shows after Patrice's stroke & after he passed away (Not just for their entertainment value, those shows transcended radio and were really moving). In particular, Dave Attell's entrance. I put his line down as the greatest I've heard on O&A ever, for multiple reasons.
Patton Oswalt, Nick Swardson, & Jim improving that movie idea.
Breuer's mother story/call.
Penn Jillette and Steven Wright's Appearances (namely when Penn and Joe Rogan were in studio at the same time).
Patrice singing with Warren Haynes (Admittedly, this meant more to me after he passed).
Jim Jefferies, Anthony and Kurt Metzer ripping on Ian Halperins "goddesses"
Opie losing his shit on management after his vacation. Admitting the show was just "rotting away"
Thanks for nothing event at the hardrock PAT FUCKING DUFFY
Announcing patrice had a strike and the show after he died were probably the best shows ive ever heard even though its for the worst reason
