I believe Paul Rudd is a national treasure. Whether you know him from Clueless or Ant-Man, the dude never really seemed to age. So this makes him the perfect person to pretend to be a millennial (which he certainly is not) in effort to get them to wear face-coverings during the pandemic.
In the cringe-worthy video, Rudd, who is 51, encourages young people to take the "save grandma challenge" and mask up. It's certainly tongue and cheek, but worth a look.
