The 'Bright' Side of the Moon: Rachel Maddow Cracks Up at Isaac Mizrahi On QVC

We're not going to lie: Watching the shopping channels is a great pastime on a hungover Sunday morning -- still LOL-ing over Mariah Carey's "moment" on HSN.

Fashion designer Isaac Mizrahi was recently on QVC selling some amah-zing cardigans (is that Mizrahi's new word for "hideous"?), and got into a heated debate with the host of the show about the true nature of the Moon...

Which prompted Rachel Maddow to hail the segment as one of the "greatest television moment[s] in history."

JUST WATCH:
