During tumultuous times, sometimes the best advice comes from toddlers.

“At my 1-year-old daughter’s nursery school, they have a handwashing song. She kept singing and washing her hands, and encouraged me and my wife to wash our songs along with the song, too,” Kazuhito (aka Daimaou) Kosaka tells The Japan Times.

Kosaka is better known as Pikotaro, the entertainer responsible for the 2016 song “PPAP (Pen-Pineapple-Apple-Pen).” He has a pen, he has an apple … I bet it’s coming back to you. That minute-long song became the most viral Japanese tune of the 2010s, reaching the ears of everyone from Justin Bieber and Donald Trump, and hundreds of millions more.
