Before her speech last Monday for the Democratic National Convention, Michigan Gov. Gretchen Whitmer mouthed something a little racy: "It's not just Shark Week -- it's Shark Week, motherfuckers."

It was was a reference to the Discovery cable channel's annual sharkfest that ended a night earlier. The comment went viral and added street cred for the governor nicknamed "Big Gretch."

On Saturday evening, she posted a photo with promo items from the cablecaster.
