When Jarom raises his voice. Whether in volume or in pitch, it's annoying. The high pitched laugh, the yelling, the goofy voices. I think he'd be well advised to move away from that schtick, but what do I know. I get he's the foil to Spencer's eternal optimism / silver linings, and I appreciate both, but when the "realistic" one is so silly or has to yell to make a point it just doesn't work for me.
Gotta say I do listen every day, though. Can't get enough of my Cougs.
