Procter & Gamble Tide detergent pods

Back in February of last year, football star Rob Gronkowski starred in a Tide commercial as a dry cleaner who rips stains out of a customer's shirt.

Now, the member of the NFL's New England Patriots has made an ad urging people not to eat Procter & Gamble's Tide pods. The commercial is being shown on the laundry brand's Twitter and Facebook pages.
