1668: "History of the Stanley Cup"

Interesting Things with JC #1668: "History of the Stanley Cup" – The Stanley Cup keeps changing hands while its silver bands record winners, mistakes, and accidents.

1666: "A Billion Seconds"

Interesting Things with JC #1666: "A Billion Seconds" - A million seconds goes by pretty fast. A billion seconds is something else entirely. Once you truly understand the difference, it changes the way you look at time, money, and the scale of the world around you.

1665: "Grizz Chapman"

Interesting Things with JC #1665: "Grizz Chapman" – Grizz was working security when a friendship with Tracy Morgan led to a 30 Rock audition, and the nearly seven-foot bouncer became one of the calmest, warmest faces on TV while fighting kidney disease off-camera.

1664: "Rob Base"

Interesting Things with JC #1664: "Rob Base" – Rob Base passed away four days after his 59th birthday, but the 1988 record he made with DJ E-Z Rock still moves crowds nearly four decades later; “It Takes Two” climbed the charts, then kept showing up at weddings, cookouts, games, and parties long after the charts moved on.
