Patrick Dempsey brings back McDreamy's signature line to promote mask-wearing

Patrick Dempsey is once again donning a mask, but it's not for the reason Grey's Anatomy fans would hope for. The star posted a selfie of him wearing a mask, along with the caption: "It's a Beautiful Day to Save Lives." Of course, fans of the ABC series immediately had a flashback of Dr Derek Shepherd in his scrubs. But for others who aren't as knowledgeable, needs to know that, this was one of Dr Shepherd's iconic quotes. While Dr Shepherd previously shared the mantra before going into dramatic surgeries, the actor is now using it to encourage the equally life-saving measure of wearing a mask during the ongoing pandemic. Dempsey is joined in his words of encouragement by numerous other celebrities, including Reese Witherspoon and Kerry Washington. Witherspoon, who lives in California where masks are mandatory, posted on Instagram: "Hey Everybody! Wearing a mask is not a political statement. It means you care about other people's health and safety. Be KIND, wear a mask!"
