Who is the old man laughing in many video clips?

Michael Rosen, also called Grandpa Nice. The loud smacking of the tongue, the spiritual raised eyebrows, the eye-catching "rabbit incisors", the magical "nice", and one expression have made this old man famous all over the world, but did you know? The person in the emoji is actually a famous British children's author. He has written many best-selling books and was once named Britain's "Fairy Tale Poet Laureate". Such a seemingly optimistic "grandpa", his life was not so lucky... In 1946, Michael Rosen was born in a Jewish family in Harrow, England. His family was poor and he was arrested twice during his college years. , was suddenly asked to resign after working at the BBC for 3 years, acute meningitis suddenly took the life of his 18-year-old son, and he was unfortunately infected with the new crown and almost died... But all of this did not hinder the grandfather's optimistic attitude, "Fate It left me full of wounds, but I responded with songs."
