Odenkirk was a writer on U.S. sketch comedy show "Saturday Night Live" before he hit the big time and he was charged with writing a monologue for guest host Irons.
Bob won an Emmy for being part of the writing team, but Irons wasn't a fan.
"(He said), 'I can sing. I can dance. I can juggle. I am a Shakespearean-trained actor. And you have me doing this?' "
Bob secretly taped the Oscar winner's outburst and played it at parties.
"I had a little recorder, and I taped it because I loved it so much," Bob said. "And he was right, God bless him. It wasn't a great monologue, but he's a trouper."
"I played it for many people. I don't know where it is now. It's at the bottom of a bin somewhere. It exists."
While his "SNL" stint earned him prestigious award, Bob Odenkirk had some regrets.
In a previous interview, he admitted he was "such a prick back then."
"I was so opinionated. I was a very opinionated comedy writer," he said. "I wish I was a sweeter fellow because I had a great opportunity there."
"I learned a lot about comedy writing and I made some great friends for life at that show, but I still wish I'd just handled it better, but don't you always wish that about your young self?"
