The chemistry between Mike and Bridgett is great here, and it does make it fun to listen to. I would love to see Bridgett make a comeback as a guest riffer. She is so good at it, and having a woman gives it a different dynamic than the sausagefest of Mike, Kevin and Bill.
For a similar thing, listen to Hor-Riff-ic Productions riffs, as that is also a husband and wife team.
