Fallon, 45, said he wants everyone to take part on Friday, March 20, at 3 p.m. ET (noon PT): “I want everyone to get out your cowbell, get out a pot and pan. 3pm – open your window or door – if you have a balcony, good for you!
“Make some noise and tell this virus to get away from us, we don’t want you. Let’s make some noise. Cowbell challenge this Friday 3 pm!”
